A slower pulse can be healthy or a warning sign, depending on symptoms, medications, and your thyroid status. Simple checks can help reveal which it is.

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.

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.

An unusually low LDL result on a screening exam can be puzzling. Learn when small numbers reflect benefit and when they might signal a hidden problem.

Regular blood donations can slowly drain iron stores, lowering hemoglobin levels. Iron supplements may help rebuild them.

Legs that repeatedly give out after activity, then recover with rest, may point to more than low minerals and warrant prompt medical evaluation.

Both systolic and diastolic readings matter. But large studies have shifted focus toward the top number. See what each reveals about heart risk.
