Prior studies observed that women experienced worse outcomes than men after myocardial infarction but did not convincingly establish an independent effect of female sex on outcomes, thus failing to impact clinical practice. Current data remain sparse and information on long-term nonfatal outcomes is lacking. To address these gaps in knowledge, we examined outcomes after incident myocardial infarction for women compared with men. ⋯ After myocardial infarction, women experience a large excess risk of recurrent myocardial infarction but not of heart failure or death independently of clinical characteristics. Future studies are needed to understand the mechanisms driving this association.

Inhibitors of the renin-angiotensin system are recommended for the management of albuminuria in patients with hypertension and diabetes mellitus, but there is little consensus about alternative therapies. Calcium channel blockers are recommended for the management of hypertension, but the data are controversial regarding their role in patients with albuminuria. This review was designed to assess the efficacy of calcium channel blockers compared with inhibitors of the renin-angiotensin system in decreasing albuminuria in diabetic, hypertensive patients with nephropathy. ⋯ Inhibitors of the renin-angiotensin system are superior to calcium channel blockers for the reduction of albuminuria in nephropathy due to hypertension and diabetes mellitus. The net clinical benefit, however, is small.

The substantial burden of heart disease promotes an interest in new ways of screening for early disease diagnosis, especially by means of noninvasive imaging. Increasing evidence for association between retinal microvascular signs and heart disease prompted us to systematically investigate the relevant current literature on the subject. ⋯ Our search yielded significant associations between retinal vascular changes, including diameter, tortuosity, and branching, and various cardiac diseases, including acute coronary syndrome, coronary artery disease, heart failure, and conduction abnormalities. The findings of our research suggest that the retinal microvasculature can provide essential data about concurrent cardiac disease status and predict future risk of cardiac-related events.

Mercury is an environmental hazard. Organic mercury is biologically more toxic than inorganic mercury. Therefore, we studied recent trends in the blood levels of organic and inorganic mercury in the United States. ⋯ Blood organic mercury increased over the period 1999-2016 in the US population, including children and pregnant women, whereas there was a steady decline in both blood inorganic mercury and urine mercury levels.

Oldest-old patients (≥85 years) constitute half the acute myocardial infarction hospitalizations among older adults and more commonly have atypical presentation, under-treatment, and functional impairments. Yet this group has not been well characterized. We characterized differences in presentation, functional impairments, treatments, health status, and mortality among middle-old (75-84 years) and oldest-old patients with myocardial infarction. ⋯ There is considerable heterogeneity in presentation, treatment, and outcomes among older patients with myocardial infarction. Mobility impairment, a marker for frailty, modifies the association between advanced age and treatments as well as outcomes.
