RESUMEN

PURPOSE: Statin drugs are effective at reducing cardiovascular events, but adherence to statin therapy remains a problem for patients and their physicians. We review a paper estimating the economic costs of poor adherence to statin drugs. METHODS: The authors examined two large databases (Medicare and Market Scan databases) including 230,000 patients with hospitalization for myocardial infarction between 2018 and 2019 to determine how many patients were not adhering to guideline-recommended anti-hyperlipidemic medications. They have also calculated the potential consequences of patients who are not adhering to the recommended therapy. RESULTS: The authors estimate that if all patients were receiving guideline-directed medical therapy, then a 22% relative risk reduction would occur in the 3-year period following discharge from the initial cardiovascular event. These findings are consistent with prior reports. This editorial discusses rationale and strategies clinicians can use to improve patients' compliance with recommendations for lipid-lowering therapy. CONCLUSION: The authors conclude that better compliance with guideline-directed lipid therapy after a cardiovascular event would lead to a large reduction in second events. Increased efforts by clinicians to improve adherence to statin therapy are warranted.

RESUMEN

PURPOSE: To identify and quantify the reasons why acute coronary syndrome (ACS) patients undergoing stenting at the University of New Mexico Hospital (UNMH) were prescribed sub-optimal dual antiplatelet therapy (DAPT) at discharge, and to identify practice patterns that could potentially lead to improved DAPT treatment for these patients. METHODS: We reviewed electronic medical records and cardiac catheterization records of 326 patients who underwent percutaneous coronary intervention (PCI) at UNMH between January 1, 2021, and June 30, 2022 and identified 229 ACS patients who survived until discharge. Demographic and clinical characteristics relevant to P2Y12 inhibitor selection were obtained from a review of medical records. Pharmacists' notes documenting their efforts to secure appropriate insurance coverage and reasons for discharging patients on clopidogrel rather than ticagrelor/prasugrel were reviewed. Patients discharged on aspirin and clopidogrel underwent review of medical records and cardiac catheterization lab records to determine if the discharge P2Y12 drug was appropriate. Reasons for inappropriate discharge on clopidogrel were categorized as cost/insurance, patient preference, concern for daily adherence to a twice-daily medication, and maintenance of pre-hospital clopidogrel therapy rather than switch to ticagrelor after PCI. RESULTS: The 229 ACS patients included 87 (38.0%) appropriately discharged on ticagrelor/prasugrel, 63 (27.5%) appropriately discharged on clopidogrel, 75 (32.8%) discharged on sub-optimal clopidogrel, and 4 (1.7%) not discharged on a P2Y12 inhibitor. For patients inappropriately discharged on clopidogrel (n = 75), the most common reasons were cost or lack of insurance (n = 56) and clinical inertia (taking clopidogrel before PCI and maintained on it afterward) (n = 17). Sub-optimal P2Y12 therapy at discharge was significantly associated with lack of insurance (odds ratio 21.5, 95% confidence interval 5.33-156,p < 0.001) but not with ethnicity, age, sex, or diabetes. CONCLUSION: At the University of New Mexico, a safety-net hospital, increasing financially restricted access to ticagrelor/prasugrel could help up to 24.5% of ACS patients reduce their risk of ischemic events. For patients admitted on clopidogrel DAPT, escalating to ticagrelor/prasugrel could reduce ischemic risk in 7.4%. Expanding and improving healthcare insurance coverage might reduce the frequency of discharge on sub-optimal P2Y12 therapy.

RESUMEN

Ellis type 4 coronary artery perforation (CAP4), also referred to as Ellis type 3 cavity-spilling perforation, is a rare but life-threatening complication of percutaneous coronary intervention characterized by extravasation of blood into a cardiac chamber, anatomic cavity, or coronary sinus or vessel. CAP4 is uncommon, accounting for 1.9% to 3.0% of all CAP. Only 11 cases of CAP4 have been reported in detail; we report an additional two cases and review prior reports of this rare complication. Our first case highlights a patient with chronic anginal symptoms due to a 75% concentric stenotic lesion in the mid-LAD. Revascularization was complicated by perforation during pre-dilation with robust contrast extravasation into the left ventricle. Successful postperforation hemostasis was achieved with heparin reversal and covered stent placement. The second case demonstrates another major mechanism of CAP4: wire perforation. During intervention, the absence of blood flow distal to the lesion in the setting of an ST segment elevation myocardial infarction obscured the course of the nonhydrophilic floppy wire leading to perforation that was managed conservatively. In our scoping review, we found that the majority of CAP4 occurred in the LAD. The most frequently involved cavity was the left ventricle-other cavities involved were the right ventricle and coronary veins. Common etiologies of CAP4 included guidewire perforation (62%) and balloon dilation (31%). Perforation was managed with reversal of anticoagulation in 46% of cases, prolonged balloon inflation in 54% of cases, and covered stent deployment in 15% of cases. No patients required surgical repair or pericardiocentesis and perforations were successfully sealed in all cases. In-hospital mortality was 0%.

RESUMEN

OBJECTIVE: The first clinical manifestation of coronary artery disease (CAD) varies widely from unheralded myocardial infarction (MI) to mild, incidentally detected disease. The primary objective of this study was to quantify the association between different initial CAD diagnostic classifications and future heart failure. METHODS: This retrospective study incorporated the electronic health record of a single integrated health care system. Newly diagnosed CAD was classified into a mutually exclusive hierarchy as MI, CAD with coronary artery bypass graft (CABG), CAD with percutaneous coronary intervention, CAD only, unstable angina, and stable angina. An acute CAD presentation was defined when the diagnosis was associated with a hospital admission. New heart failure was identified after the CAD diagnosis. RESULTS: Among 28 693 newly diagnosed CAD patients, initial presentation was acute in 47% and manifested as MI in 26%. Within 30 days of CAD diagnosis, MI [hazard ratio (HR) = 5.1; 95% confidence interval: 4.1-6.5] and unstable angina (3.2; 2.4-4.4) classifications were associated with the highest heart failure risk (compared to stable angina), as was acute presentation (2.9; 2.7-3.2). Among stable, heart failure-free CAD patients followed on average 7.4 years, initial MI (adjusted HR = 1.6; 1.4-1.7) and CAD with CABG (1.5; 1.2-1.8) were associated with higher long-term heart failure risk, but an initial acute presentation was not (1.0; 0.9-1.0). CONCLUSION: Nearly 50% of initial CAD diagnoses are associated with hospitalization, and these patients are at high risk of early heart failure. Among stable CAD patients, MI remained the diagnostic classification associated with the highest long-term heart failure risk, however, having an initial acute CAD presentation was not associated with long-term heart failure.

RESUMEN

Cardiac catheterization laboratory (CCL) morbidity and mortality conferences (MMCs) are a critical component of CCL quality improvement programs and are important for the education of cardiology trainees and the lifelong learning of CCL physicians and team members. Despite their fundamental role in the functioning of the CCL, no consensus exists on how CCL MMCs should identify and select cases for review, how they should be conducted, and how results should be used to improve CCL quality. In addition, medicolegal ramifications of CCL MMCs are not well understood. This document from the American College of Cardiology's Interventional Section attempts to clarify current issues and options in the conduct of CCL MMCs and to recommend best practices for their conduct.

RESUMEN

BACKGROUND: Many cardiac conditions require long-term clinical follow-up to monitor progression of disease and tolerance and adherence to therapies. Providers are often unsure as to the frequency of clinical follow-up and who should provide the follow-up. In the absence of formal guidance, patients may be seen more frequently than necessary - thereby limiting clinic space for other patients, or not frequently enough, potentially leading to undetected progression of disease. OBJECTIVES: To determine the extent to which guidelines (GL)/consensus statements (CS) provide guidance about appropriate follow-up for common cardiovascular conditions. METHODS: We identified 31 chronic cardiovascular disease conditions for which long-term (beyond 1 year) follow-up is indicated and used PubMed and professional society websites to identify all relevant GL/CS (n = 33) regarding these chronic cardiac conditions. RESULTS: Of the 31 cardiac conditions reviewed, GL/CS contained no recommendation or vague recommendation for long-term follow-up for 7 of the conditions. Of the 24 conditions with recommendations for follow-up, 3 had recommendations for imaging follow-up only without mention of clinical follow-up. Of the 33 GL/CS reviewed, 17 made any recommendations about long-term follow-up. When recommendations were made regarding follow-up, they were often vague, using terminology such as "as needed". CONCLUSIONS: Half of GL/CS fail to provide recommendations for clinical follow-up of common cardiovascular conditions. Writing groups for GL/CS should adopt a standard of routinely including recommendations for follow-up including specific advice about level of expertise needed (eg, primary care physician, cardiologist), need for imaging or testing, and frequency of follow-up.
