Controlling blood pressure and blood sugar will help both your heart and your kidneys.

On the surface, it's difficult to see how coronary artery disease and kidney damage might be related. But on the cellular level, the two conditions often go hand in hand. A closer look reveals the key. Underlying both conditions are two powerful risk factors: high blood pressure and diabetes, each of which damages the heart and kidneys independently.

CT angiography is one of several tests doctors can use to assess your heart's arteries.

For more than half a century, cardiologists have relied on a procedure known as invasive coronary angiography, a test that can reveal dangerous narrowings in the arteries that supply the heart. The test uses a special dye that shows up on x-rays, which is delivered to the heart through a thin tube (catheter) that's snaked through a blood vessel in the leg or arm. As a result, rare but sometime serious complications can occur, including bleeding at the insertion site or damage to the artery.

Divorce—especially for women—appears to boost the odds of having a heart attack, a new study finds.

The study, in the April 14, 2015, Circulation: Cardiovascular Quality and Outcomes, included nearly 16,000 adults ages 45 to 80 who had been married at least once. By the end of the 18-year study, more than a third had gone through at least one divorce. Heart attacks were 24% more common in once-divorced women and 77% higher in those divorced at least twice.

High cholesterol is a key culprit in the development of cardiovascular disease, the leading cause of death in the United States and many other developed countries. We know that lowering cholesterol helps prevent heart attacks and strokes. But an unanswered question remains: how low should you go? New research published online today in The New England Journal of Medicine suggests that lower is better. In a large clinical trial, participants who took a cholesterol-lowering statin plus ezetimibe, a different type of cholesterol-lowering drug, had lower levels of harmful LDL cholesterol and experienced fewer heart attacks and strokes than participants taking a statin alone. The new findings provide a strong rationale for using ezetimibe when a statin alone isn’t enough.

One in six people worldwide will have a stroke in his or her lifetime. Learn to recognize a "brain attack."

Heart attacks often make themselves known with a hard-to-ignore, obvious symptom like chest pain. That's not the case for strokes, which can cause a wide range of symptoms that may affect your ability to speak, see, move, or feel. A stroke interrupts blood flow to the brain, depriving brain cells of oxygen and nutrients. Prompt treatment can prevent a potentially devastating disability or death—which is why everyone should know the top warning signs of stroke.

A strong or weak hand grip carries more than just social cues. It may also help measure an individual’s risk for having a heart attack or stroke, or dying from cardiovascular disease. As part of the international , researchers measured grip strength in nearly 140,000 adults in 17 countries and followed their health for an average of four years. Each 11-pound decrease in grip strength over the course of the study was linked to a 16% higher risk of dying from any cause, a 17% higher risk of dying from heart disease, a 9% higher risk of stroke, and a 7% higher risk of heart attack. Interestingly, grip strength was a better predictor of death or cardiovascular disease than blood pressure. What’s the connection? It’s possible that grip strength measures biological age.

Substantial research proves the Mediterranean and DASH eating plans offer important health benefits for men.

Family history or past smoking both point to higher risk for this potentially fatal condition.

How many "lifesaving" medical tests have you been offered lately? One frequently marketed to older men is an ultrasound of the abdominal aorta, the large artery below the heart that feeds the lower body. A bulging weak spot there—an abdominal aortic aneurysm (AAA)—could eventually rupture, and that is usually fatal.

Maintaining a healthy weight is the best way to rein in gastroesophageal reflux disease (GERD), or chronic heartburn, according to a study in The American Journal of Gastroenterology. Researchers found that GERD symptoms increased for every incremental rise in body mass index (BMI), which measures the ratio of weight to height.

In GERD, the acidic contents of the stomach back up into the lower esophagus, causing burning pain. The most effective treatment for GERD is taking an acid-reducing proton-pump inhibitor medication, such as omeprazole (Prilosec). People who are overweight are much more likely to develop GERD.

A fainting spell can be inconsequential, or it can signal a serious health issue. It's important to learn why you faint.
