Longitudinal persistence with secondary prevention therapies relative to patient risk after myocardial infarction.

ABSTRACT: Prior studies have demonstrated that patients with high-risk acute myocardial infarction (AMI) are less likely to receive guideline-directed medications during hospitalisation. It is unknown if this paradox persists following discharge. We aimed to assess if persistence with guideline-directed medications post discharge varies by patients' risk following AMI.Data were analysed from two prospective, multicentre US AMI registries. The primary outcome was persistence with all prescribed guideline-directed medications (aspirin, ?-blockers, statins, angiotensin-antagonists) at 1, 6 and 12 months post discharge. The association between risk and medication persistence post discharge was assessed using multivariable mixed-effect models.Among 6434 patients with AMI discharged home, 2824 were considered low-risk, 2014 intermediate-risk and 1596 high-risk for death based upon their Global Registry of Acute Coronary Event (GRACE) 6-month risk score. High-risk was associated with a lower likelihood of receiving all appropriate therapies at discharge compared with low-risk patients (relative risk (RR) 0.90; 95% CI 0.87 to 0.94). At 12 months, the rate of persistence with all prescribed therapies was 61.5%, 57.9% and 45.9% among low-risk, intermediate-risk and high-risk patients, respectively. After multivariable adjustment, high-risk was associated with lower persistence with all prescribed medications (RR 0.87; 95% CI 0.82 to 0.92) over follow-up. Similar associations were seen for individual medications. Over the 5?years of the study, persistence with prescribed therapies post discharge improved modestly among high-risk patients (RR 1.05; 95% CI 1.03 to 1.08 per year).High-risk patients with AMI have a lower likelihood of persistently taking prescribed medications post discharge as compared with low-risk patients. Continued efforts are needed to improve the use of guideline-directed medications in high-risk patients.

Project description:BACKGROUND/OBJECTIVES:Secondary prevention medications are recommended for older adults after acute myocardial infarction (AMI), but little is known about whether nursing home (NH) residents receive these medications. The objective was to evaluate new use of secondary prevention medications after AMI in NH residents who were previously nonusers and to evaluate what factors were associated with use. DESIGN:Retrospective cohort using linked national Minimum Data Set assessments; Online Survey, Certification and Reporting records; and Medicare claims. SETTING:U.S. NHs. PARTICIPANTS:National cohort of 11,192 NH residents aged 65 and older who were hospitalized for an AMI between May 2007 and March 2010, had no beta-blocker or statin use for 4 months or longer before the hospitalization, and survived 14 days or more after NH readmission. MEASUREMENTS:The outcome was the number of secondary prevention medications initiated within 30 days of NH readmission. RESULTS:Thirty-seven percent of residents had no secondary prevention medications initiated after AMI, 41% had 1 initiated, and 22% had 2 initiated. After covariate adjustment, fewer secondary prevention medications were used in older residents (proportional odds ratio (POR) = 0.48, 95% confidence interval (CI) = 0.40-0.57 for ?95 vs 65-74); women (POR = 0.88, 95% CI = 0.80-0.96);and those with a do-not-resuscitate (DNR) order (POR = 0.90, 95% CI = 0.83-0.98), functional impairment (dependent or totally dependent vs independent to limited assistance, POR = 0.77, 95% CI = 0.69-0.86), and cognitive impairment (moderate to severe vs no impairment, POR = 0.79, 95% CI = 0.70-0.89). CONCLUSION:More than one-third of older NH residents in the United States do not have any secondary prevention medications initiated after AMI, with fewer medications initiated in older residents; women; and those with, DNR orders, poor physical function, and cognitive impairment. A lack of evidence about the safety and effectiveness of secondary preventions medications in the NH population and unmeasured person-centered goals of care are plausible explanations for these findings.

Project description:ImportanceLow socioeconomic status (SES) is associated with poor long-term prognosis after myocardial infarction (MI). Plausible underlying mechanisms have received limited study.ObjectiveTo assess whether SES is associated with risk factor target achievements or with risk-modifying activities, including cardiac rehabilitation programs, monitoring, and drug therapies, during the first year after MI.Design, setting, and participantsThis cohort study included a population-based consecutive sample of 30 191 one-year survivors of first-ever MI who were 18 to 76 years of age, resided in the general community in Sweden, were followed up until their routine 11- to 15-month revisit, and were registered in the national registry Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) from 2006 through 2013. Data analyses were performed from January to August 2020.ExposureIndividual-level SES by proxy disposable income quintile. Secondary exposures were educational level and marital status.Main outcomes and measuresOdds ratios (ORs) with 95% CIs for achieved risk factor targets at the 1-year revisit and for use of guideline-recommended secondary prevention activities.ResultsThe study comprised 30 191 participants (72.9% men) with a mean (SD) age of 63.0 (8.6) years. Overall, higher SES was associated with better target achievements and use of most secondary prevention. The highest (vs lowest) income quintile was associated with achieved smoking cessation (OR, 2.05; 95% CI, 1.78-2.35), target blood pressure levels (OR, 1.17; 95% CI, 1.07-1.27), and glycated hemoglobin levels (OR, 1.57; 95% CI, 1.19-2.06). The highest-income quintile was associated not only with participation in physical training programs (OR, 2.28; 95% CI, 2.11-2.46) and patient educational sessions (OR, 2.29; 95% CI, 2.12-2.47) in cardiac rehabilitation but also with more monitoring of lipid profiles (OR, 1.20; 95% CI, 1.08-1.33) and intensification of statin therapy (OR, 1.22; 95% CI, 1.11-1.35) during the first year after MI. One year after MI, the highest-income quintile was associated with persistent use of statins (OR, 1.26; 95% CI, 1.10-1.45), high-intensity statins (OR, 1.10; 95% CI, 1.00-1.21), and renin-angiotensin-aldosterone system inhibitors (OR, 1.27; 95% CI, 1.08-1.49).Conclusions and relevanceFindings indicated that, in a publicly financed health care system, higher SES was associated with better achievement of most risk factor targets, programs aimed at lifestyle change, and evidence-based drug therapies after MI. Observed differences in secondary prevention activity may be a factor in higher long-term risk of recurrent disease among individuals with low SES.

Project description:Background A risk score for secondary prevention after myocardial infarction (Thrombolysis in Myocardial Infarction Risk Score for Secondary Prevention [TRS2P]), based on 9 established clinical factors, was recently developed from the TRA 2°P- TIMI 50 (Thrombin Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events) trial. We aimed to evaluate the performance of TRS 2P for predicting long-term outcomes in real-world patients presenting for coronary angiography. Methods and Results A retrospective analysis of 13 593 patients referred to angiography for the assessment or treatment of coronary disease was performed. Risk stratification for 10-year major adverse cardiovascular events was performed using the TRS 2P, divided into 6 categories (0 to ≥5 points), and in relation to the presenting coronary syndrome. All clinical variables, except prior coronary artery bypass grafting, were independent risk predictors. The annualized incidence rate of major adverse cardiovascular events increased in a graded manner with increasing TRS 2P, ranging from 1.65 to 16.6 per 100 person-years ( Ptrend<0.001). Compared with the lowest-risk group (risk indicators=0), the hazard ratios (95% CIs) for 10-year major adverse cardiovascular events were 1.60 (95% CI, 1.36-1.89), 2.58 (95% CI, 2.21-3.02), 4.31 (95% CI, 3.69-5.05), 6.43 (95% CI, 5.47-7.56), and 10.03 (95% CI, 8.52-11.81), in those with 1, 2, 3, 4 and ≥5 risk indicators, respectively. Risk gradation was consistent among individual clinical end points. TRS 2P showed reasonable discrimination with C-statistics of 0.693 for major adverse cardiovascular events and 0.758 for mortality. The graded relationship between the risk score and event rates was observed in both patients presenting with acute and nonacute coronary syndromes. Conclusions The use of TRS 2P, a simple risk score based on routinely collected variables, enables risk stratification in patients undergoing coronary angiography. Its predictive value was demonstrated in a real-world setting with long-term follow-up and regardless of the acuity of coronary presentation.
