Beta-blockers provide a differential survival benefit in patients with coronary artery disease undergoing contemporary post-percutaneous coronary intervention management.

ABSTRACT: Beta-adrenergic receptor blockers are used in patients with coronary artery disease (CAD) to reduce the harmful effects of excessive adrenergic activation on the heart. However, there is limited evidence regarding the benefit of beta-blockers in the context of contemporary management following percutaneous coronary intervention (PCI). We used the nationwide South Korea National Health Insurance database to identify 87,980 patients with a diagnosis of either acute myocardial infarction (AMI; n = 38,246) or angina pectoris (n = 49,734) who underwent PCI between 2013 and 2017, and survived to be discharged from hospital. Beta-blockers were used in a higher proportion of patients with AMI (80.6%) than those with angina (58.9%). Over a median follow-up of 2.2 years (interquartile range 1.2-3.3 years) with the propensity-score matching analysis, the mortality risk was significantly lower in patients treated with a beta-blocker in the AMI group (HR: 0.78; 95% CI 0.69-0.87; p < 0.001). However, the mortality risk was comparable regardless of beta-blocker use (HR: 1.07; 95% CI 0.98-1.16; p = 0.10) in the angina group. The survival benefit associated with beta-blocker therapy was most significant in the first year after the AMI event.

Project description:BackgroundElevated lipoprotein(a) (Lp[a]) is a risk factor for first atherosclerotic thrombosis events, but the role of elevated Lp(a) in secondary prevention is controversial. This study aimed to retrospectively investigate the influence of elevated Lp(a) levels on the prognosis of patients with coronary artery disease.MethodsThe team collected and compared clinical information of patients hospitalized during percutaneous coronary intervention (PCI). This study used a multivariate logistic regression model to evaluate the relationships between Lp(a) levels, cardiovascular risk factors, and the prognosis of coronary artery disease in patients undergoing PCI.ResultsThere were no statistically significant differences between patients grouped according to Lp(a) level in terms of sex; age; body mass index and obesity; hyperuricemia; smoking; cardiac insufficiency; acute myocardial infarction; multivessel lesion; in-stent restenosis; secondary PCI; apolipoprotein AI level; incidence of high total cholesterol or high low-density lipoprotein cholesterol; or family history of hypertension, diabetes, or coronary artery disease. The average Lp(a) concentration did not statistically significantly decrease after 1 year of statin treatment after PCI. One year after patients began statins, there were no significant differences between Lp(a) groups in the incidence of high triglycerides (P = .13), high total cholesterol (P = .52), or high low-density lipoprotein cholesterol (P = .051). Multivariate logistic regression analysis indicated that diabetes (P = .02) was associated with in-stent restenosis, whereas diabetes (P = .02) and multivessel lesions (P < .001) were associated with secondary PCI in patients who underwent coronary angiography 1 year after PCI. Compared with normal Lp(a) levels, high Lp(a) levels did not significantly increase the incidence of in-stent restenosis or secondary PCI in patients who underwent coronary angiography 1 year after PCI.ConclusionSustained high concentrations of Lp(a) did not significantly increase the incidence of in-stent restenosis or secondary PCI in patients who underwent coronary angiography 1 year after PCI.

Project description:ImportanceIt is uncertain whether coronary artery bypass grafting (CABG) is associated with cognitive decline in older adults compared with a nonsurgical method of coronary revascularization (percutaneous coronary intervention [PCI]).ObjectiveTo compare the change in the rate of memory decline after CABG vs PCI.Design, setting, and participantsRetrospective cohort study of community-dwelling participants in the Health and Retirement Study, who underwent CABG or PCI between 1998 and 2015 at age 65 years or older. Data were modeled for up to 5 years preceding and 10 years following revascularization or until death, drop out, or the 2016-2017 interview wave. The date of final follow-up was November 2017.ExposuresCABG (including on and off pump) or PCI, ascertained from Medicare fee-for-service billing records.Main outcomes and measuresThe primary outcome was a summary measure of cognitive test scores and proxy cognition reports that were performed biennially in the Health and Retirement Study, referred to as memory score, normalized as a z score (ie, mean of 0, SD of 1 in a reference population of adults aged ≥72 years). Memory score was analyzed using multivariable linear mixed-effects models, with a prespecified subgroup analysis of on-pump and off-pump CABG. The minimum clinically important difference was a change of 1 SD of the population-level rate of memory decline (0.048 memory units/y).ResultsOf 1680 participants (mean age at procedure, 75 years; 41% female), 665 underwent CABG (168 off pump) and 1015 underwent PCI. In the PCI group, the mean rate of memory decline was 0.064 memory units/y (95% CI, 0.052 to 0.078) before the procedure and 0.060 memory units/y (95% CI, 0.048 to 0.071) after the procedure (within-group change, 0.004 memory units/y [95% CI, -0.010 to 0.018]). In the CABG group, the mean rate of memory decline was 0.049 memory units/y (95% CI, 0.033 to 0.065) before the procedure and 0.059 memory units/y (95% CI, 0.047 to 0.072) after the procedure (within-group change, -0.011 memory units/y [95% CI, -0.029 to 0.008]). The between-group difference-in-differences estimate for memory decline for PCI vs CABG was 0.015 memory units/y (95% CI, -0.008 to 0.038; P = .21). There was statistically significant increase in the rate of memory decline after off-pump CABG compared with after PCI (difference-in-differences: mean increase in the rate of decline of 0.046 memory units/y [95% CI, 0.008 to 0.084] after off-pump CABG), but not after on-pump CABG compared with PCI (difference-in-differences: mean slowing of decline of 0.003 memory units/y [95% CI, -0.024 to 0.031] after on-pump CABG).Conclusions and relevanceAmong older adults undergoing coronary revascularization with CABG or PCI, the type of revascularization procedure was not significantly associated with differences in the change of rate of memory decline.

Project description:BackgroundPatients with peripheral arterial disease (PAD) have known to a high risk of cardiac mortality. However, the effectiveness of the routine evaluation of coronary arteries such as routine coronary angiography (CAG) in PAD patients receiving percutaneous transluminal angioplasty (PTA) is unclear.MethodsA total of 765 consecutive PAD patients underwent successful PTA and 674 patients (88.1%) underwent routine CAG. Coronary artery disease (CAD) was defined as angiographic stenosis ≥70%. Patients were divided into three groups; 1) routine CAG and a presence of CAD (n = 413 patients), 2) routine CAG and no CAD group (n = 261 patients), and 3) no CAG group (n = 91 patients). To adjust for any potential confounders that could cause bias, multivariable Cox-proportional hazards regression and propensity score matching (PSM) analysis was performed. Clinical outcomes were evaluated by Kaplan-Meier curved analysis at 5-year follow-up.ResultsIn this study, the 5-year survival rate of patients with PAD who underwent PTA was 88.5%. Survival rates were similar among the CAD group, the no CAD group, and the no CAG group, respectively (87.7% vs. 90.4% vs. 86.8% P = 0.241). After PSM analysis between the CAD group and the no CAD group, during the 5-year clinical follow-up, there were no differences in the incidence of death, myocardial infarction, strokes, peripheral revascularization, or target extremity surgeries between the two groups except for repeat PCI, which was higher in the CAD group than the non-CAD group (9.3% vs. 0.8%, P<0.001).ConclusionPAD patients with CAD were expected to have very poor long-term survival, but they are shown no different long-term prognosis such as mortality compared to PAD patients without CAD. These PAD patients with CAD had received PCI and/or optimal medication treatment after the CAG. Therefore a strategy of routine CAG and subsequent PCI, if required, appears to be a reasonable strategy for mortality risk reduction of PAD patients. Our results highlight the importance for evaluation for CAD in patients with PAD.
