Warm weather, vein valve issues, and fluid retention can all puff up your ankles. Learn what doctors look for and simple steps that may ease it.

The scientific understanding of HDL cholesterol has evolved in recent years, and many cardiologists now believe that HDL may be more of a bystander rather than a "good guy" that helps lower heart disease risk. While some types of HDL are great at plucking excess cholesterol from LDL and artery walls (a process referred to as reverse cholesterol transport) other types of HDL don't do this. In clinical trials, medications to raise HDL levels-including a drug specifically designed to improve reverse cholesterol transport-have not succeeded in lowering heart attacks and strokes.

Chronic pain is linked to an increased risk of high blood pressure, which may be driven in part by depression, according to a 2026 study. Mind-body therapies and medications may help.

High temperatures raise risk for heat exhaustion and heat stroke, and also stress the cardiovascular system, making the heart work harder. If you have a heart condition, here's how to keep cool and protect yourself when temperatures rise.

Seasons can affect blood pressure. But winter chills, holiday weight gain, and salty comfort foods can also push readings higher as warm weather gives way to cold.

If you have high triglycerides, fruit sugar is only part of the story. Carbs, alcohol, weight, exercise, and healthy fats all influence this number.

Carbohydrate intake and other aspects of your diet may impact triglyceride levels. See how everyday choices may nudge this number up or down.

After a heart attack, a cardiac rehab program comprised of supervised exercise, lifestyle coaching, and emotional support can reshape daily habits and lower the odds of future trouble.

A low HDL number can be worrisome even with normal cholesterol. Explore lifestyle shifts that may nudge your good cholesterol higher.
