- Background Differences in comorbidity, pharmacotherapy, cardiovascular (CV) outcome, and mortality between myocardial infarction (MI) patients and peripheral arterial disease (PAD) patients are not well documented. Aim The aim of this study was to compare comorbidity, treatment patterns, CV outcome, and mortality in MI and PAD patients, focusing on sex differences. Methods This observational, population-based study used data retrieved from mandatory Swedish national registries. The risks of MI and death were assessed by Kaplan-Meier analysis. Secondary preventive drug use was characterized. Cox proportional risk hazard modelling was used to determine the risk of specific events. Results Overall, 91,808 incident MI patients and 52,408 PAD patients were included. CV mortality for MI patients at 12, 24, and 36 months after index was 12.3%, 19.3%, and 25.4%, and for PAD patients it was 15.5%, 23.4%, and 31.0%. At index, 89% of MI patients and 65% of PAD patients used aspirin and 74% and 53%, respectively, used statins. Unlike MI women, women with PAD had a lower rate of other CV-related comorbidities and a lower risk of CV events (age-adjusted hazard ratio 0.81, 95% confidence interval 0.79-0.84), CV death (0.78, 0.75-0.82), and all-cause death (0.78, 0.76-0.80) than their PAD male counterparts. Conclusion PAD patients were less intensively treated and had a higher CV mortality than MI patients. Women with PAD were less likely than men to present with established polyvascular disease, whereas the opposite was true of women with MI. This result indicates that the lower-limb vasculature may more often be the index site for atherosclerosis in women.

- Background-Long-term disease progression after myocardial infarction (MI) is inadequately understood. We evaluated the pattern and angiographic properties (culprit lesion [CL]/non-CL [NCL]) of recurrent MI (re-MI) in a large real-world patient population. Methods and Results--Our observational study used prospectively collected data in 108 615 patients with first-occurrence MI enrolled in the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) between July 1, 2006 and November 29, 2014. During follow-up (median, 3.2 years), recurrent hospitalization for MI occurred in 11 117 patients (10.2%). Of the patients who underwent coronary angiography for the index MI, a CL was identified in 44 332 patients. Of those patients, 3464 experienced an re-MI; the infarct originated from the NCL in 1243 patients and from the CL in 655 patients. In total, 1566 re-MIs were indeterminate events and could not be classified as NCL or CL re-MIs. The risk of re-MI within 8 years related to the NCL was 0.06 (95% confidence interval [CI], 0.05-0.06), compared with 0.03 (95% CI, 0.02-0.03) for the CL. There were no large differences in baseline characteristics of patients with subsequent NCL versus CL re-MIs. Independent predictors of NCL versus CL re- MI were multivessel disease (odds ratio, 2.29; 95% CI, 1.87-2.82), male sex (odds ratio, 1.36; 95% CI, 1.09-1.71), and a prolonged time between the index and re-MI (odds ratio, 1.16; 95% CI, 1.10- 1.22). Conclusions--In a large cohort of patients with first-occurrence MI undergoing percutaneous coronary intervention, the risk of re-MI originating from a previously untreated lesion was twice higher than the risk of lesions originating from a previously stented lesion.
