Obesity is associated with the development of atrial fibrillation and may impact atrial fibrillation-related outcomes. To date, no anthropometric measure is included in any risk stratification scheme for stroke and death in atrial fibrillation patients. ⋯ Overweight and obesity are risk factors for "ischemic stroke, thromboembolism or death" in patients with atrial fibrillation, even after adjustment for CHADS2 and CHA2DS2-VASc scores. The association between BMI and outcomes among atrial fibrillation patients may be modified by sex.

The phenomenon of silent myocardial infarction is poorly understood. ⋯ Silent myocardial infarctions are more common than previously thought. One of 4 patients with suspected coronary artery disease had experienced a silent myocardial infarction; the extent in average is 10% of the left ventricle, and it is more common in diabetics.

Cigarette smoking is a well-known cardiovascular risk factor and its impact on cardiovascular disease is even greater among people with diabetes. The aim of this study is to compare the prevalence and determinants of smoking among US adults with diabetes or impaired fasting glucose, and those without diabetes or impaired fasting glucose. ⋯ In the US, smoking prevalence among people with diabetes and impaired fasting glucose has not changed and is comparable with the nondiabetic population. Tobacco control efforts should be intensified among this population at high risk for complications and mortality.

Randomized Controlled Trial
Systolic blood pressure and cardiovascular outcomes during treatment of hypertension.
Randomized controlled trials in hypertension demonstrate cardiovascular benefits when systolic blood pressures are reduced from higher values to<160 mm Hg. The value of lower targets has not been fully defined, although major guidelines recommend achieving systolic blood pressures of<140 mm Hg. This study was conducted to explore cardiovascular outcomes at differing on-treatment blood pressure levels. ⋯ In high-risk hypertensive patients, major cardiovascular events are significantly lower in those with systolic blood pressures<140 mm Hg and<130 mm Hg than in those with levels>140 mm Hg. There are stroke benefits at levels<120 mm Hg, but they are offset by increased coronary events. Renal function is best protected in the 130 to 139 mm Hg range.
