RESUMEN
Coronary CT angiography (CTA) derived fractional flow reserve (FFRCT) is recommended for physiological assessment in intermediate coronary stenosis for guiding referral to invasive coronary angiography (ICA). In this study, we report real-world data on the feasibility of implementing a CTA/FFRCT test algorithm as a gatekeeper to ICA at referral hospitals. Retrospective all-comer study of patients with new onset stable symptoms and suspected coronary stenosis (30-89%) by CTA. Evaluation of CTA datasets, interpretation of FFRCT analysis, and decisions on downstream testing were performed by skilled CT-cardiologists. CTA was performed in 3974 patients, of whom 381 (10%) were referred directly to ICA, whereas 463 (12%) to non-invasive functional testing: FFRCT 375 (81%) and perfusion imaging 88 (19%). FFRCT analysis was rejected in 8 (2%) due to inadequate CTA image quality. Number of patients deferred from ICA after FFRCT was 267 (71%), while 100 (27%) were referred to ICA. Obstructive coronary artery disease (CAD) was confirmed in 62 (62%) patients and revascularization performed in 53 (53%). Revascularization rates, n (%), were higher in patients undergoing FFRCT-guided versus CTA-guided referral to ICA: 30-69% stenosis, 28 (44%) versus 8 (21%); 70-89% stenosis, 39 (69%) versus 25 (46%), respectively, both p < 0.05. Implementation of FFRCT at referral hospitals was feasible, reduced the number of invasive procedures, and increased the revascularization rate.
RESUMEN
In modern clinical practice, less than half of new-onset heart failure (HF) patients undergo ischemic evaluation, and only a minority undergo revascularization. We aimed to assess the proportion of the effect of hypertension (antihypertensive treatment) on incident HF to be eliminated by prevention of CHD event treated with or without revascularization, considering possible treatment-mediator interaction. Causal mediation analysis of ALLHAT included 42,418 participants (age 66.9±7.7; 35.6% black, 53.2% men). A new CHD event (myocardial infarction or angina) that occurred after randomization but before the incident HF outcome was the mediator. Incident symptomatic congestive HF (CHF) and hospitalized/fatal HF (HHF) were the primary and secondary outcomes. Logistic regression (for mediator) and Cox proportional hazards regression (for outcome) were adjusted for demographics, cardiovascular disease history, and risk factors. During a median 4.5-year follow-up, 2,785 patients developed CHF, including 2,216 HHF events. Participants who developed CHD events had twice the higher incidence rate of CHF than CHD-free (28.5 vs 13.9 events/ 1,000 person-years). The proportion of reference interaction indicating direct harm due to CHD event for lisinopril (234% for CHF; 355% for HHF) and amlodipine (244% for CHF; 468% for HHF) was greater than for chlorthalidone (143% for CHF; 269% for HHF). In patients with revascularized CHD events, chlorthalidone and amlodipine eliminated 21-24%, and lisinopril - 45% of HHF. Antihypertensive treatment was not able to eliminate harm from CHD events treated without revascularization. In conclusion, the antihypertensive drugs (chlorthalidone, lisinopril, amlodipine) prevent HF not principally by preventing CHD events but via other pathways. HF is moderated but not mediated by CHD events. Revascularization of CHD events is paramount for HF prevention.
RESUMEN
Background: Myocardial revascularization surgery (MRV) is a revascularization therapy for coronary artery disease aimed at improving survival conditions. Elderly patients with increased comorbidities undergoing MRV face challenges in preventing postoperative complications, including atrial fibrillation (AF), a common arrhythmia occurring in 40% of cases or even in 80% of cases if the procedure is combined with valve surgery. This study aimed to determine the risk factors associated with the appearance of postoperative AF (POAF) in patients undergoing isolated MRV. Methods: This is an epidemiological, retrospective, and analytical case-control study (90 cases and 360 controls). Results: Mortality within the group of patients who presented with POAF in the study population was 15.5%, and 9.44% in the control group. Logistic regression showed an association of AF with the presurgical variables age >60 years and urgent/emergency surgery and the postsurgical variables cardiogenic shock, blood transfusion, pulmonary edema, pleural effusion, orotracheal reintubation, and mechanical ventilation time. Conclusions: Strategies should be proposed for the timely identification of risk factors and postoperative complications related to AF onset to avoid the increased morbidity and mortality associated with this type of arrhythmia during the postoperative period.

Background: The debate on percutaneous coronary intervention (PCI) of the unprotected left main coronary artery (LMCA) has been constant over time. Objective: To investigate the clinical and procedural characteristics and cardiovascular outcomes of PCI of unprotected LMCA. Material and methods: Observational study which included patients with unprotected LMCA disease undergoing PCI; patients with cardiogenic shock prior to the procedure were excluded. We describe the clinical and angiographic characteristics, as well as the major adverse cardiac and cerebrovascular events (MACCE) according to the year of the procedure. Results: We included 73 patients, with a SYNTAX I score of 31.2 ± 9.1, mostly with ST-elevation acute coronary syndrome (35%). There was a higher frequency of triple vessel coronary disease (63%) and distal LMCA lesions (35%). The provisional stent technique was the most used for distal lesions (58%) and the 2-stent technique for bifurcation lesions (78%), supported by intravascular ultrasound (IVUS) in 38%. During follow-up, 19 presented MACCE (26%), out of which cardiac death occurred in 13%, non-cardiovascular death in 5%, non-fatal acute myocardial infarction in 1%, cerebrovascular event in 2%, and revascularization of the treated vessel in 4%. Conclusions: It was observed a similar frequency to the one appearing in other studies of cardiovascular events, mainly in patients with intermediate risk, which supports the increasing use of percutaneous intervention in this population.

A 74-year-old man presented with symptoms and noninvasive diagnostic studies suggestive of myocardial infarction. Coronary angiography revealed total occlusion of the distal right coronary artery with a unique accessory coronary ring that provided retrograde collateral flow to the left ventricle, demonstrating the importance of considering non-native vessels when identifying target lesions.
RESUMEN
BACKGROUND AND OBJECTIVES: The clinical benefits of complete revascularization (CR) in acute myocardial infarction (AMI) patients are unclear. Moreover, the benefit of CR is unknown in AMI with diabetes mellitus (DM) patients. We sought to compare the prognosis of CR and incomplete revascularization (IR) in patients with AMI and multivessel disease, according to the presence of DM. METHODS: A total of 2,150 AMI patients with multivessel coronary artery disease were analyzed. CR was defined based on the angiographic image. The primary endpoint of this study was the patient-oriented composite outcome (POCO) defined as a composite of all-cause death, any myocardial infarction, and any revascularization within 3 years. RESULTS: Overall, 3-year POCO was significantly lower in patients receiving angiographic CR (985 patients, 45.8%) compared with IR (1,165 patients, 54.2%). When divided into subgroups according to the presence of DM, CR reduced 3-year clinical outcomes in the non-DM group but not in the DM group (POCO: 11.7% vs. 23.2%, p<0.001, any revascularization: 7.2% vs. 10.8%, p=0.024 in the non-DM group, POCO: 24.3% vs. 27.8%, p=0.295, any revascularization: 13.3% vs. 11.3%, p=0.448 in the DM group, for CR vs. IR). Multivariate analysis showed that CR significantly reduced 3-year POCO (hazard ratio, 0.52; 95% confidence interval, 0.36-0.75) only in the non-DM group. CONCLUSIONS: In AMI patients with multivessel disease, CR may have less clinical benefit in DM patients than in non-DM patients.
RESUMEN
Introduction: Despite the large amount of researches addressed the issue of the relationship between the intensity of preoperative symptoms of depression and/ or anxiety with their postoperative intensity and any complications after surgery, there have been almost unaddressed such subjects as how the patients perceive their own capabilities or physical attractiveness, and the emotions which are evoked by various aspects of their own bodies, including postoperative scars. These aspects play a significant role in assessing the quality of patients' life and have a significant impact on the overall assessment of the surgery as an event, in both the short- and long-term perspective. Aim: To evaluate the relationship between anxiety, pain level, self-efficacy and body esteem in the pre- and postoperative periods among patients scheduled for coronary artery bypass surgery. Material and methods: Prospective studies were carried out in a group of 50 patients scheduled for coronary artery bypass surgery, either on a planned or urgent basis. Anxiety, both as a state and as a trait, was assessed using the Polish version of the State-Trait Anxiety Inventory (STAI). The Visual Analogue Scale (VAS) was employed to evaluate pain. The Self-Efficacy Gauge measured self-efficacy, while the Body Esteem Scale assessed body esteem. Results and Conclusions: The intensity of state anxiety significantly negatively correlated with self-efficacy following CABG surgery. There was a statistically significant negative correlation between the intensity of painand self-efficacy in the postoperative period. Among female patients, the intensity of pain, both pre- and post-operatively, negatively correlated with their assessment of body esteem concerning physical condition at the respective time points. When assessing anxiety as a trait during the perioperative period, a positive correlation with pain intensification after CABG was identified.

Objectives: To identify predictors of coronary artery bypass graft surgery (CABG) requirement as a revascularization method in in real-world non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients. Materials and methods: . An individual pre-specified analysis of patients with NSTE-ACS was performed from two prospective Argentine registries between 2017 and 2022. We analyzed the difference in baseline characteristics between patients who required CABG and those who did not require this intervention. Then, a logistic regression analysis was performed to determine independent predictors in patients who received CABG as a method of revascularization. Results: A total of 1848 patients with a median age of 54.8 (interquartile range [IQR]: 53.7-56) years and an ejection fraction of 42.1% (IQR: 41.2-43.1) were included. A total of 233 patients required CABG (12.6%). Baseline characteristics between the two groups were similar, except in patients requiring CABG, who were younger (51.5 vs. 55.7 years; p=0.010), more frequently diabetic (38.2% vs. 25.7%; p=0.001) and male (90.1% vs. 73.7%; p=0.001). In addition, they had, to a lesser extent, previous cardiac surgery (2.1% vs. 11.2%; p=0.011). After multivariable analysis, the following were independently associated with CABG: age (Odds Ratio [OR]: 0.99, 95% confidence interval [CI]: 0.98-0.99; p=0.008), male sex (OR: 3.08, 95% CI: 1.87-5.1; p=0.001), history of previous CABG (OR: 0.14, 95% CI: 0.05-0.30; p=0.001) and diabetes (OR: 1.84, 95% CI: 1.31- 2.57; p=0.001). Conclusions: In this analysis of two NSTEACS registries, younger age, male sex, a diagnosis of diabetes and the absence of previous surgery were independent predictors of the requirement for inpatient CABG.
RESUMEN
BACKGROUND: Significant controversy continues to confound patient selection and referral for revascularization and mitral valve intervention in patients with ischemic cardiomyopathy (ICM). Cardiac magnetic resonance (CMR) enables comprehensive phenotyping with gold-standard tissue characterization and volumetric/functional measures. Therefore, we sought to determine the impact of CMR-enriched phenomapping patients with ICM to identify differential outcomes following surgical revascularization and surgical mitral valve intervention (sMVi). METHODS: Consecutive patients with ICM referred for CMR between 2002 and 2017 were evaluated. Latent class analysis was performed to identify phenotypes enriched by comprehensive CMR assessment. The primary end point was death, heart transplant, or left ventricular assist device implantation. A multivariable Cox survival model was developed to determine the association of phenogroups with overall survival. Subgroup analysis was performed to assess the presence of differential response to post-magnetic resonance imaging procedural interventions. RESULTS: A total of 787 patients were evaluated (63.0±11.2 years, 24.8% women), with 464 primary events. Subsequent surgical revascularization and sMVi occurred in 380 (48.3%) and 157 (19.9%) patients, respectively. Latent class analysis identified 3 distinct clusters of patients, which demonstrated significant differences in overall outcome (P<0.001). Latent class analysis identified differential survival benefit of revascularization in patients as well as patients who underwent revascularization with sMVi, based on phenogroup classification, with phenogroup 3 deriving the most survival benefit from revascularization and revascularization with sMVi (hazard ratio, 0.61 [0.43-0.88]; P=0.0081). CONCLUSIONS: CMR-enriched unsupervised phenomapping identified distinct phenogroups, which were associated with significant differential survival benefit following surgical revascularization and sMVi in patients with ICM. Phenomapping provides a novel approach for patient selection, which may enable personalized therapeutic decision-making for patients with ICM.

Background: Pain control after off-pump coronary artery bypass graft (OPCAB) facilitates mobilization and improves outcomes. The efficacy of the erector spinae plane block (ESPB) after cardiac surgery remains controversial. Methods: We aimed to investigate the analgesic effects of ESPB after OPCAB. Precisely 56 patients receiving OPCAB were randomly divided into ESPB and control groups. The primary outcome was visual analog scale (VAS) pain scores at 6, 12, 24, and 48 h postoperatively. Secondary outcomes were the dose of rescue analgesics in terms of oral morphine milligram equivalents, the dose of antiemetics, the length of intubation time, and the length of stay in the intensive care unit (ICU). Results: The VAS scores were similar at all time points in both groups. The incidence of severe pain (VAS score > 7) was significantly lower in the ESPB group (50% vs. 15.4%; p = 0.008). The dose of rescue analgesics was also lower in the ESPB group (19.04 ± 18.76, 9.83 ± 12.84, p = 0.044) compared with the control group. The other secondary outcomes did not differ significantly between the two groups. Conclusions: ESPB provides analgesic efficacy by reducing the incidence of severe pain and opioid use after OPCAB.
RESUMEN
Objectives: Minimally-invasive direct coronary artery bypass (MIDCAB) is a less-invasive alternative to full sternotomy off-pump coronary artery bypass (FS-OPCAB) revascularization of the left anterior descending artery (LAD). Some studies suggested that MIDCAB is associated with a greater risk of graft occlusion and repeat revascularization than FS-OPCAB LIMA-to-LAD grafting. Data comparing MIDCAB to FS-OPCAB with regard to long-term follow-up is scarce. We compared short- and long-term results of MIDCAB vs. FS-OPCAB revascularization over a maximum follow-up period of 10 years. Patients and methods: From December 2009 to June 2020, 388 elective patients were included in our retrospective study. 229 underwent MIDCAB, and 159 underwent FS-OPCAB LIMA-to-LAD grafting. Inverse probability of treatment weighting (IPTW) was used to adjust for selection bias and to estimate treatment effects on short- and long-term outcomes. IPTW-adjusted Kaplan-Meier estimates by study group were calculated for all-cause mortality, stroke, the risk of repeat revascularization and myocardial infarction up to a maximum follow-up of 10 years. Results: MIDCAB patients had less rethoracotomies (n = 13/3.6% vs. n = 30/8.0%, p = 0.012), fewer transfusions (0.93 units ± 1.83 vs. 1.61 units ± 2.52, p < 0.001), shorter mechanical ventilation time (7.6 ± 4.7â h vs. 12.1 ± 26.4â h, p = 0.005), and needed less hemofiltration (n = 0/0% vs. n = 8/2.4%, p = 0.004). Thirty-day mortality did not differ significantly between the two groups (n = 0/0% vs. n = 3/0.8%, p = 0.25). Long-term outcomes did not differ significantly between study groups. In the FS-OPCAB group, the probability of survival at 1, 5, and 10 years was 98.4%, 87.8%, and 71.7%, respectively. In the MIDCAB group, the corresponding values were 98.4%, 87.7%, and 68.7%, respectively (RR1.24, CI0.87-1.86, p = 0.7). In the FS group, the freedom from stroke at 1, 5, and 10 years was 97.0%, 93.0%, and 93.0%, respectively. In the MIDCAB group, the corresponding values were 98.5%, 96.9%, and 94.3%, respectively (RR0.52, CI0.25-1.09, p = 0.06). Freedom from repeat revascularization at 1, 5, and 10 years in the FS-OPCAB group was 92.2%, 84.7%, and 79.5%, respectively. In the MIDCAB group, the corresponding values were 94.8%, 90.2%, and 81.7%, respectively (RR0.73, CI0.47-1.16, p = 0.22). Conclusion: MIDCAB is a safe and efficacious technique and offers comparable long-term results regarding mortality, stroke, repeat revascularization, and freedom from myocardial infarction when compared to FS-OPCAB.
RESUMEN
OBJECTIVES: Left internal mammary artery (LIMA) graft stenoses detected at early coronary angiography may be reversible and consequently prompt unnecessary graft revision. We aim to investigate the frequency, natural course, and clinical significance of internal mammary artery graft stenosis upon early angiography in patients undergoing hybrid myocardial revascularization. METHODS: In this retrospective sub-study of the Coronary Hybrid Revascularization Study, we compared graft appearance, ie, stenosis degree and flow, on early (in-hospital) and scheduled follow-up coronary angiography after 1 year. We assessed the change in graft patency using the Fitzgibbon classification (grade A: unimpaired runoff; grade B > 50% stenosis; grade O: occlusion), as well as graft association with adverse events (death, myocardial infarction, stroke, and repeat revascularization) at up to 5-year follow-up. RESULTS: We report clinical follow-up data for all 131 patients included in the Coronary Hybrid Revascularization Study. Change in graft patency was analyzed in 86 patients with satisfactory visualization of the LIMA graft on early and follow-up coronary angiography. All LIMA grafts were patent at discharge and follow-up. Twenty-seven of 37 (73%) grade B graft stenoses at early angiography resolved to grade A during follow-up of median 12 months (range, 8-83 months) after surgery. Angiographically significant graft stenoses at early coronary angiography were not associated with adverse clinical outcome up to 5-year follow-up. CONCLUSIONS: Our results suggest that the majority of clinically silent LIMA graft stenoses resolve during follow-up and are not associated with adverse clinical outcomes.
RESUMEN
Early stent thrombosis is a rare complication of percutaneous intervention and is associated with significant 30-day mortality. We present a novel case of multiple recurrent early stent thrombosis consistent with spontaneous vaccine-induced thrombotic thrombocytopenia. We were successfully able to manage this unusual condition through an interdisciplinary collaboration.
RESUMEN
PURPOSE OF REVIEW: Optimal therapy for patients with chronic coronary artery disease (CCD) has long been a topic under investigation and a subject of debate. Seeking to clarify appropriate management, the International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) trial compared medical management versus coronary angiography for patients with stable ischemic heart disease. Its reception in the medical community has been met with both acclaim and criticism. In light of such disparate views of this trial, a systematic review of the literature citing the ISCHEMIA trial was performed. RECENT FINDINGS: All articles citing the ISCHEMIA trial on PubMed as of July 21, 2023, were compiled and underwent qualitative analysis. A total of 430 articles were evaluated; 109 (25.3%) did not offer substantial commentary on ISCHEMIA and cite it as background evidence for further study. Of the commentary articles, the majority (224, 52.1%) gave balanced, honest appraisals of the ISCHEMIA trial. A total of 46 (10.7%) strongly praised the trial while another 39 (9.1%) were strongly critical of the results. Almost three-quarters of the literature citing the ISCHEMIA trial was commentary in nature, with roughly equal distribution across the spectrum of praise and criticism. Despite being one of the largest studies on CCD and coronary revascularization ever conducted, the impact of ISCHEMIA on the cardiology community appears to be mixed.

BACKGROUND: Autoimmune blistering disorders (ABDs) might elevate cardiovascular risk, but studies are lacking. OBJECTIVE: The objective of this study was to examine if ABDs elevate the risk of atherosclerotic cardiovascular disease, heart failure, arrhythmia, venous thromboembolism, and cardiovascular death. METHODS: A population-based cohort of Danish patients with ABD (≥18 years of age) diagnosed during 1996-2021 (n = 3322) was compared with an age- and sex-matched comparison cohort from the general population (n = 33,195). RESULTS: Compared with the general population, patients with ABDs had higher 1-year risks of atherosclerotic cardiovascular disease (3.4% vs 1.6%), heart failure (1.9% vs 0.7%), arrhythmia (3.8% vs 1.3%), venous thromboembolism (1.9% vs 0.3%), and cardiovascular death (3.3% vs 0.9%). The elevated risk persisted after 10 years for all outcomes but arrhythmia. The hazard ratios associating ABDs with the outcomes during the entire follow-up were 1.24 (1.09-1.40) for atherosclerotic cardiovascular disease, 1.48 (1.24-1.77) for heart failure, 1.16 (1.02-1.32) for arrhythmia, 1.87 (1.50-2.34) for venous thromboembolism, and 2.01 (1.76-2.29) for cardiovascular death. The elevated cardiovascular risk was observed for both pemphigus and pemphigoid. LIMITATIONS: Our findings might only generalize to patients with ABDs without prevalent cardiovascular diseases. CONCLUSION: Patients with ABDs had an elevated cardiovascular risk compared with age- and sex-matched controls.

AIMS: The present analysis from the Functional Assessment in Elderly Myocardial Infarction Patients with Multivessel Disease (FIRE) trial aims to explore the significance of pre-admission physical activity and assess whether the benefits of physiology-guided complete revascularization apply consistently to sedentary and active older patients. METHODS AND RESULTS: Patients aged 75 years or more with myocardial infarction (MI) and multivessel disease were randomized to receive physiology-guided complete revascularization or culprit-only strategy. The primary outcome was a composite of death, MI, stroke, or any revascularization within a year. Secondary endpoints included the composite of cardiovascular death or MI, as well as single components of the primary endpoint. Pre-admission physical activity was categorized into three groups: (i) absent (sedentary), (ii) light, and (iii) vigorous. Among 1445 patients, 692 (48%) were sedentary, whereas 560 (39%) and 193 (13%) performed light and vigorous physical activity, respectively. Patients engaging in light or vigorous pre-admission physical activity exhibited a reduced risk of the primary outcome compared with sedentary individuals [light hazard ratio (HR) 0.70, 95% confidence interval (CI) 0.55-0.91 and vigorous HR 0.14, 95% CI 0.07-0.91, respectively]. These trends were also observed for death, cardiovascular death, or MI. When comparing physiology-guided complete revascularization vs. culprit-only strategy, no significant interaction was observed for primary and secondary endpoints when stratified by sedentary or active status. CONCLUSION: In older patients with MI, pre-admission physical activity emerges as a robust and independent prognostic determinant. Physiology-guided complete revascularization stands out an effective strategy in reducing ischaemic adverse events, irrespective of pre-admission physical activity status. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT03772743.
The Functional Assessment in Elderly Myocardial Infarction Patients with Multivessel Disease (FIRE) trial has shown that physiology-guided complete revascularization reduces ischaemic adverse events in older patients with myocardial infarction (MI) and multivessel disease. Older patients who engage in light or vigorous physical activity before hospitalization for MI have a reduced risk of the primary composite outcome of death, MI, stroke, or ischaemia-driven revascularization. These benefits extend to all secondary cardiovascular outcomes as well. In the present subanalysis of the FIRE trial, we find that the positive prognosis associated with physiology-guided complete revascularization holds true even for patients with a sedentary lifestyle. This means that this type of revascularization can effectively reduce ischaemic adverse events in older patients with MI and multivessel disease, regardless of their physical activity levels.
