A stroke occurs when blood cannot reach the brain. In about 80 percent of strokes, a blood clot prevents blood flow to the brain. These are called ischemic strokes. Sometimes, blood accumulates in the brain, or in the spaces surrounding it. This causes hemorrhagic strokes.
Both binge drinking and long-term heavy drinking can lead to strokes even in people without coronary heart disease. Recent studies show that people who binge drink are about 56 percent more likely than people who never binge drink to suffer an ischemic stroke over 10 years. Binge drinkers also are about 39 percent more likely to suffer any type of stroke than people who never binge drink.
In addition, alcohol exacerbates the problems that often lead to strokes, including hypertension, arrhythmias, and cardiomyopathy.
Chronic alcohol use, as well as binge drinking, can cause high blood pressure, or hypertension. Your blood pressure is a measurement of the pressure your heart creates as it beats, and the pressure inside your veins and arteries. Healthy blood vessels stretch like elastic as the heart pumps blood through them. Hypertension develops when the blood vessels stiffen, making them less flexible. Heavy alcohol consumption triggers the release of certain stress hormones that in turn constrict blood vessels.This elevates blood pressure. In addition, alcohol may affect the function of the muscles within the blood vessels, causing them to constrict and elevate blood pressure.
KNOW THE BENEFITS :
Research shows that healthy people who drink moderate amounts of alcohol may have a lower risk of developing coronary heart disease than nondrinkers. Moderate drinking is usually defined as no more than two drinks in a given day for men and one drink per day for women who are not pregnant or trying to conceive.
A variety of factors, including diet, genetics, high blood pressure, and age, can cause fat to build up in your arteries, resulting in coronary heart disease. An excess of fat narrows the coronary arteries, which are the blood vessels that supply blood directly to the heart. Clogged arteries reduce blood supply to the heart muscle, and make it easier for blood clots to form. Blood clots can lead to both heart attacks and strokes.
According to recent studies, drinking moderately can protect your heart from these conditions. Moderate drinking helps inhibit and reduce the build-up of fat in the arteries. It can raise the levels of HDL—or “good” cholesterol—in the blood, which wards off heart disease. It can help guard against heart attack and stroke by preventing blood clots from forming and by dissolving blood clots that do develop. Drinking moderately also may help keep blood pressure levels in check.
These benefits may not apply to people with existing medical conditions, or who regularly take certain medications. In addition, researchers discourage people from beginning to drink just for the health benefits. Rather, you can use this research to help you spark a conversation with your medical professional about the best path for you.
