When is it safe to have sex after a heart attack?

Most men can resume regular sexual activity after a heart attack once they can engage in mild-to-moderate physical activity without issues, such as 10 to 20 minutes of brisk walking or climbing one or two flights of stairs. That means no chest pain, shortness of breath, lightheadedness, or extreme fatigue with exertion.

Looking past blood pressure numbers

For decades, blood pressure treatment was dictated by a person’s numbers, with a blood pressure less than 140/90 millimeters of mercury (mm Hg) considered normal. But evidence has proved this to be an inadequate goal. Research now suggests an individualized approach to managing blood pressure that considers other heart health risks, lifestyle habits, and family history may be a better way to ward off heart attacks and strokes.

This unusual syndrome causes your heart to race when you stand up

A rapid heart rate—tachycardia—is a key feature of postural orthostatic tachycardia syndrome, or POTS, a mysterious condition that involves the nervous system and can cause a constellation of symptoms, including fatigue, shortness of breath, headaches, and brain fog, as well as pain in the chest, extremities, or elsewhere in the body. At least half of all cases of POTS are thought to be triggered by an infection (such as mononucleosis), which then spurs inflammation or an autoimmune response. Treatment includes drinking lots of water, eating lots of salt, and graded exercise training.

Stroke prevention in atrial fibrillation: Beyond anti-clotting drugs

People with atrial fibrillation who develop or face a high risk of serious bleeding from anti-clotting drugs may be candidates for procedures that block or remove a part of the heart where dangerous blood clots form. About 90% of blood clots in the heart form in the left atrial appendage (LAA), a small pouch that protrudes from the top of the heart. Two procedures prevent clots from escaping from the LAA and causing a stroke. One delivers a device that blocks the opening of the LAA; the other removes most of the LAA during heart surgery done for another reason.

Better blood sugar tracking: A benefit for heart health?

A continuous glucose monitor (CGM)—a small device placed on the arm or belly that measures blood sugar every few minutes—may help people with diabetes recognize the eating and exercise habits that hinder (or help) them control their blood sugar. CGM readouts, which are displayed on a smartphone or portable monitor, show your blood sugar values, trends, and the percentage of time that your blood sugar is in a ”good control” range. Medicare covers CGMs for people who inject insulin at least three times a day or use an insulin pump to control their blood sugar.
