RESUMEN

AIM: Malnutrition is associated with the development of atherosclerosis and an increased risk of cardiovascular mortality in elderly patients. The present study aimed to investigate the association between the Geriatric Nutritional Risk Index (GNRI), a simple nutritional assessment tool, and the prevalence of peripheral artery disease (PAD) in elderly coronary artery disease patients. METHODS: We evaluated 228 elderly coronary artery disease patients (mean age 74.0 ± 5.7 years). Ankle-brachial index (ABI) measurements were routinely carried out to investigate the prevalence of lower extremity PAD. Patients showing ABI <0.9 were defined as having PAD. RESULTS: Based on our findings, 20.6% of the study patients had PAD. The median GNRI values were significantly lower in patients with PAD than those in patients without PAD (93.8 vs 100.0, P < 0.001). Even after multivariate adjustment, GNRI values were independently associated with PAD (odds ratio 0.94; 95% confidence interval 0.89-0.99; P = 0.024). Furthermore, patients with low GNRI and high C-reactive protein levels had a 5.5-fold higher risk of having PAD than those with high GNRI and low C-reactive protein levels. CONCLUSIONS: GNRI values showed a strong relationship with PAD in elderly coronary artery disease patients. These data reinforce the utility of GNRI as a screening tool in clinical practice.

RESUMEN

BACKGROUND: Coronary artery calcification (CAC) is an independent predictor of cardiovascular morbidity and mortality in chronic kidney disease (CKD) patients. The aim of the present study was to evaluate the predictive value of CAC scores for the incidence of contrast-induced nephropathy (CIN) after cardiac catheterization in non-dialyzed CKD patients. METHODS: The present study evaluated a total of 140 CKD patients who underwent cardiac catheterization. Patients were stratified into two groups based on the optimal cut-off value of the CAC score, which was graded by a non-triggered, routine diagnostic chest computed tomography scan: CAC score ≥8 (high CAC group); and CAC score <8 (low CAC group). CIN was defined as an increase of >10 % in the baseline serum cystatin C level at 24 h after contrast administration. RESULTS: The mean estimated glomerular filtration rate levels were 41.1 mL/min/1.73 m2, and the mean contrast dose administered was 37.5 mL. Patients with high CAC scores exhibited a higher incidence of CIN than patients with low CAC scores (25.5 vs. 3.2 %, p < 0.001). After multivariate adjustment for confounders, the CAC score predicted CIN (odds ratio 1.68, 95 % confidence interval 1.28-2.21, p < 0.001). Moreover, the C-index for CIN prediction significantly increased when the CAC scores were added to the Mehran risk score (0.855 vs. 0.760, p = 0.023). CONCLUSION: CAC scores, as evaluated using semi-quantitative methods, are a simple and powerful predictor of CIN. Incorporating the CAC score in the Mehran risk score significantly improved the predictive ability to predict CIN incidence.

RESUMEN

AIMS: Previous studies have shown that aortic valve calcification (AVC) was associated with cardiovascular events and mortality. On the other hand, periprocedural myocardial injury (PMI) in percutaneous coronary intervention (PCI) is a well-known predictor of subsequent mortality and poor clinical outcomes. The purpose of the study was to assess the hypothesis that the presence of AVC could predict PMI in PCI. METHODS: This study included 370 patients treated with PCI for stable angina pectoris. AVC was defined as bright echoes ＞1 mm on one or more cusps of the aortic valve on ultrasound cardiography (UCG). PMI was defined as an increase in high-sensitivity troponin T level of ＞5 times the upper normal limit (＞0.070 ng/ml) at 24 hours after PCI. RESULTS: AVC was detected in 45.9% of the patients (n=170). The incidence of PMI was significantly higher in the patients with AVC than in those without AVC (43.5% vs 21.0%, p＜0.001). The presence of AVC independently predicted PMI after adjusting for other significant variables (odds ratio 2.26, 95% confidence interval 1.37-3.74, p=0.002). Other predictors were male sex, age, estimated glomerular filtration rate, and total stent length. Furthermore to predict PMI, adding AVC to the established risk factors significantly improved the area under the receiver operating characteristic curves, from 0.68 to 0.72, of the PMI prediction model (p=0.025). CONCLUSION: The presence of AVC detected in UCG could predict the incidence of PMI.

RESUMEN

PURPOSE: Statin therapy usually increases HDL-C levels. However, a paradoxical decrease in HDL-C levels after statin therapy is often seen in clinical settings. The relationship between a paradoxical decrease in HDL-C levels after statin therapy and adverse cardiovascular events in patients with stable angina pectoris (SAP) is not well understood. The purpose of this study was to analyze the relationship between paradoxical HDL-C decreases after statin therapy and major adverse cardiovascular events (MACEs) in patients undergoing percutaneous coronary intervention (PCI) for SAP. METHODS: Between January 2006 and March 2015, 867 patients underwent PCI for SAP. Of them, we enrolled 209 patients who were newly started on statin therapy before PCI. We excluded patients who had started statin therapy earlier than 6 months before PCI, patients who had not started statin therapy after PCI, and patients who were diagnosed with acute coronary syndrome. They were divided into 2 groups according to the change in their HDL-C levels between baseline and 6 to 9 months after the index PCI: decreased HDL group after statin treatment (80 patients) and increased HDL group (129 patients). The primary end points were MACEs defined as a composite of all-cause death, nonfatal acute myocardial infarction, and target vessel revascularization (TVR). FINDINGS: Using Kaplan-Meier analysis, the 7-year event rate for composite MACEs in the decreased HDL group was found to be higher than that for the increased HDL group (38% versus 24%, log-rank P = 0.02). TVR occurred more frequently in the decreased HDL group than in the increased HDL group (32% versus 12%, log-rank P = 0.01). With the use of multivariate analysis, changes in HDL-C levels after statin therapy indicated a significant inverse association with the increased risk of MACEs, (hazard ratio [HR] = 0.94; 95% CI, 0.92-0.97; P < 0.01). The incidence of MACEs was more strongly associated with ΔHDL than with ΔLDL. Moreover, BMS usage also independently predicted MACEs (HR = 2.18; 95% CI, 1.14-4.17; P < 0.01). IMPLICATIONS: A paradoxical decrease in HDL-C levels after statin therapy might be a risk factor for MACEs, especially TVR, in patients with SAP.

RESUMEN

BACKGROUND AND AIMS: Visceral adipose tissue (VAT), unlike subcutaneous adipose tissue (SAT), is highly correlated with cardiovascular risk factors. This study aimed to evaluate the predictive value of adipose tissue composition, as measured by computed tomography, for cardiovascular events in patients with stable coronary artery disease. METHODS: 357 consecutive patients who underwent 64-slice computed tomography and elective percutaneous coronary intervention (PCI) were recruited. The ratio of visceral to subcutaneous adipose tissue (VAT/SAT) was calculated. Patients were divided into three groups in accordance with VAT/SAT (low VAT/SAT, <0.55 [<25th percentile]; moderate VAT/SAT, 0.55-1.03 [25th-75th percentile]; high VAT/SAT, ≥1.03 [≥75th percentile]). The investigated risk factors were hypertension, hyperglycaemia, and dyslipidaemia. We analysed the incidence of major adverse cardiovascular events (MACE), defined as the composite of cardiac death, myocardial infarction, and any revascularization. RESULTS: The rate of patients with two or more concomitant risk factors was significantly higher in the high VAT/SAT group (p = 0.006). During 1480 person-years, 109 events were documented. There was a significant association between the incidence of MACE and VAT/SAT, with the worst event-free survival rate in the high VAT/SAT group (log-rank, p = 0.01). In Cox analysis, the hazard ratio of high VAT/SAT for MACE was 2.72 (95% confidence interval 1.04-7.09, p = 0.04) compared with the low VAT/SAT after adjustment for confounding factors. CONCLUSIONS: Increased VAT/SAT is independently associated with the incidence of MACE, indicating that adipose tissue composition is a useful predictor of cardiovascular outcome, after elective PCI.

RESUMEN

OBJECTIVE: Heparin is not recommended to be administered during the interruption of antiplatelet therapy for non-cardiac surgery. However, there are insufficient data to determine the value. The purpose of the present study was to evaluate the clinical results of the administration of unfractionated heparin during the interruption of antiplatelet therapy in non-cardiac surgery patients who had previously undergone drug-eluting stent (DES) implantation. METHODS: We retrospectively identified 210 elective non-cardiac surgical procedures that were performed with the administration of unfractionated heparin during interruption of all antiplatelet therapies in patients who had previously undergone DES implantation. Heparin was administered during the perioperative period in accordance with the local practice guideline at out institution. We examined the clinical outcomes within 30 days of surgery. RESULTS: The mean number of implanted DESs was 2.1±1.3. No major adverse cardiac events (including cardiac death, definite stent thrombosis, and non-fatal myocardial infarction) occurred in any of the 210 cases within 30 days of surgery. Four of the 210 cases (1.9%) required reoperation for bleeding within 30 days of surgery. CONCLUSION: Our data showed the potential for the perioperative management with unfractionated heparin administration in Japanese patients who had previously undergone DES implantation who required non-cardiac surgery with the interruption of all antiplatelet therapies.

RESUMEN

Coronary artery bypass grafting (CABG) is an established treatment for multivessel coronary artery disease. However, problematic situations are occasionally encountered after CABG, such as disease progression in the native coronary artery with graft occlusion, which causes difficulty in revascularization. The purpose of this study was to evaluate changes in the native coronary artery after CABG. Between 2009 and 2012 in our institution, 351 patients underwent CABG, and 768 bypass grafts were anastomosed to non-occluded coronary arteries. Of these, 489 bypass grafts had available early postoperative angiographic results (≤6 months) suitable for assessment in this study. We defined malignant graft failure after CABG to be bypass graft occlusion and de novo complete occlusion of the target native coronary artery proximal to the graft anastomosis site. In the early angiographic results, 17 grafts were occluded (17/489; 3.5 %). Two of the grafts displayed malignant graft failure (a saphenous vein graft to the right coronary artery and a saphenous vein graft to the diagonal branch) (2 of 17 occluded grafts, and 2 of 489 studied grafts). Of the patent bypass grafts, 24 involved progression to occlusion in the proximal native coronary artery (19 saphenous vein grafts, 4 left internal thoracic artery grafts, and 1 right internal thoracic artery graft). Malignant graft failure was uncommon during short-term follow-up after CABG. At the same time, disease progression in the proximal native coronary artery from stenosis to occlusion following patent bypass grafting was relatively common, especially for vein grafts.

RESUMEN

BACKGROUND: Estimated glomerular filtration rate (eGFR) and proteinuria are both important determinants of the risk of cardiovascular disease and mortality. The aim of the present study was to investigate the independent and combined effects of eGFR and proteinuria on tissue characterization of the coronary plaques of culprit lesions. METHODS AND RESULTS: Conventional intravascular ultrasound and 3-D integrated backscatter intravascular ultrasound (IB-IVUS) were performed in 555 patients undergoing elective percutaneous coronary intervention. They were divided into 2 groups according to the absence or presence of proteinuria (dipstick result ≥1+). Patients with proteinuria had coronary plaque with significantly greater percentage lipid volume compared with those without (43.6±14.8% vs. 48.6±16.1%, P=0.005). Combined analysis was done using eGFR and absence or presence of proteinuria. Subjects with eGFR 45-59 ml/min/1.73 m2 and proteinuria were significantly more likely to have higher percent lipid volume compared with those with eGFR >60 ml/min/1.73 m2 without proteinuria. After multivariate adjustment for confounders, the presence of proteinuria proved to be an independent predictor for lipid-rich plaque (OR, 1.85; 95% CI: 1.12-3.06, P=0.016). CONCLUSIONS: The addition of proteinuria to eGFR level may be of value in the risk stratification of patients with coronary artery disease.

RESUMEN

BACKGROUND: Statins are reportedly effective in the primary and secondary prevention of cardiovascular disease, mainly due to their ability to aggressively reduce low-density lipoprotein cholesterol (LDL-C) levels. However, patients sometimes exhibit the so-called "statin escape" phenomenon. The purpose of our study was to investigate the impact of the statin escape phenomenon on long-term clinical outcomes in patients with acute myocardial infarction (AMI). METHOD: This was a subgroup analysis of 1144 patients from the Nagoya Acute Myocardial Infarction Study (NAMIS) treated between January 2004 and December 2012. We analyzed 660 patients who initiated statin treatment after AMI. Statin escape phenomenon was defined as an increase in the LDL-C levels during the 9-month treatment period by >10% of the initial values after 4 weeks of initiating statin treatment. Patients were divided into two groups depending on whether they exhibited the statin escape phenomenon, with 474 patients in the non-escape group and 186 patients in the escape group. RESULT: Compared to the non-escape group, the escape group showed significantly lower LDL-C levels at 4 weeks after treatment initiation (81.3 ± 20.1 mg/dL vs. 101.1 ± 25.4 mg/dL, P < 0.01). By contrast, the escape group showed significantly higher LDL-C levels at 9 months after treatment initiation (105.8 ± 28.3 mg/dL vs. 90.3 ± 22.6 mg/dL, P < 0.01). Major adverse cardiac and cerebrovascular events (MACCE; a composite of all-cause death, MI, and stroke) were more frequent in the escape group than in the non-escape group (10.8% vs. 6.1%, P = 0.03). Multivariate analysis showed that statin escape phenomenon was an independent predictor of MACCE (hazard ratio: 2.02, 95% confidence interval: 1.11-3.66, P = 0.02). CONCLUSION: Statin escape phenomenon may be an independent predictor of long-term clinical outcomes in AMI patients.

RESUMEN

BACKGROUND: Both airflow limitation and smoking are established cardiovascular risk factors. However, their interaction as risk factors for the development of atherosclerosis in coronary artery disease patients remains unclear. OBJECTIVES: To evaluate the effect of the interaction between airflow limitation and smoking status on the severity of carotid atherosclerosis. METHODS: We categorized the 234 enrolled patients with coronary artery disease into four groups: never-smokers with normal pulmonary function (group A), never-smokers with airflow limitation (group B), ever-smokers with normal pulmonary function (group C), and ever-smokers with airflow limitation (group D). RESULTS: The prevalence of airflow limitation in the enrolled patients was 23.1% (ever-smokers: 15.8%, never-smokers: 7.3%). The prevalence of severe carotid atherosclerosis was 28.2, 29.4, 41.3, and 45.9%, respectively, in the four groups (group D vs. group A, p = 0.035). Even after multivariate adjusting for confounding factors, ever-smokers with airflow limitation were independently associated with severe carotid atherosclerosis (odds ratio 2.89, 95% confidence interval, 1.19-7.00, p = 0.019). CONCLUSIONS: Ever-smokers with airflow limitation were significantly associated with severe carotid atherosclerosis among patients with coronary artery disease. These findings also provide additional insight into the correlation between airflow limitation and poor cardiovascular clinical outcomes.

RESUMEN

Statin therapy moderately increases high-density lipoprotein cholesterol (HDL-C) levels. Contrary to this expectation, a paradoxical decrease in HDL-C levels after statin therapy is seen in some patients. We evaluated 724 patients who newly started treatment with statins after acute myocardial infarction (AMI). These patients were divided into 2 groups according to change in HDL-C levels between baseline and 6 to 9 months after initial AMI (ΔHDL). In total, 620 patients had increased HDL-C levels and 104 patients had decreased HDL-C levels. Both groups achieved follow-up low-density lipoprotein cholesterol levels <100 mg/dl. Adverse cardiovascular events (a composite of all-cause death, myocardial infarction, and stroke) have more frequently occurred in the decreased HDL group compared with the increased HDL group (15.4% vs 7.1%, p = 0.01). Multivariate analysis showed that decreased HDL, onset to balloon time, and multivessel disease were the independent predictors of adverse cardiovascular events (hazard ratio [HR] 1.95, 95% confidence interval [CI] 1.08 to 3.52; HR 1.05, 95% CI 1.01 to 1.09; and HR 2.08, 95% CI 1.22 to 3.56, respectively). In conclusion, a paradoxical decrease in serum HDL-C levels after statin therapy might be an independent predictor of long-term adverse cardiovascular events in patients with AMI.

RESUMEN

Albuminuria has traditionally been associated with an elevated risk of cardiovascular events. However, few studies have examined the potential relation between albuminuria and periprocedural risk in percutaneous coronary intervention (PCI). The aim of this study was to evaluate the impact of albuminuria on the incidence of periprocedural myocardial injury (PMI) in patients who underwent PCI. The study included 252 consecutive patients who underwent PCI. The incidence of PMI was significantly higher in patients with albuminuria than in those with normoalbuminuria (31.9% vs 43.3%, respectively, p = 0.014). Even after adjustment for confounders, the presence of albuminuria predicted PMI (odds ratio 2.07, 95% confidence interval 1.08 to 3.97, p = 0.029). Furthermore, patients with albuminuria and preserved estimated glomerular filtration rate had a 4.2-fold higher risk for PMI than did patients with normoalbuminuria and preserved estimated glomerular filtration rate. In conclusion, albuminuria was a strong predictor of PMI in patients who underwent PCI.

RESUMEN

BACKGROUND: Diabetic retinopathy has been identified as a predictor of cardiovascular events and heart failure in patients with diabetes mellitus (DM). This study aimed to assess the impact of diabetic retinopathy on the incidence of late cardiac events following percutaneous coronary intervention. METHODS: We enrolled 88 consecutive DM patients who underwent elective percutaneous coronary intervention and whose ophthalmologic records were available. Patients were divided into 2 groups: those with diabetic retinopathy (DR+ group; n=47), and those without diabetic retinopathy (DR- group; n=41). We examined the incidence of major adverse cardiac events (MACE) including cardiac death, myocardial infarction, and acute heart failure requiring emergency admission over a period of up to 5 years. RESULTS: Patients in the DR+ group were likely to have a lower estimated glomerular filtration rate. Kaplan-Meier analysis showed that the event-free survival rates for all MACE, myocardial infarction, and heart failure were significantly lower in the DR+ group than in the DR- group (p=0.002, p=0.025, and p=0.022, respectively). Multivariate Cox proportional hazards analysis indicated that the presence of DR was a significant predictor of MACE (hazard ratio: 8.7; 95% CI: 1.1-69.8, p=0.042). CONCLUSION: The presence of DR might be a useful predictor of late cardiac events following percutaneous coronary intervention.
