Influence of polyphenols in wine and health
The French population has a low mortality from coronary heart disease incidenciade, despite a high consumption of fat. Epidemiological situation is known as the “French paradox” and has been explained by the moderate intake of wine, common in this population.
Numerous studies have linked effect of ingesting a moderate amount of wine, with the presence of polyphenolic compounds in it. Polyphenols have a strong interest in its antioxidant effect, which appears to be associated with anticarcinogenic and antiatherogenic properties attributed to these components present in wine, but are also present in many foods of plant origin. These properties of common foods such as vegetables, fruits, nuts and vegetable foods in general, may explain some of the virtues of the Mediterranean diet, and open a new field of research in nutrition-oriented prevention of cardiovascular diseases and tumors.
Warning Signs and Prevention to Heart Attack (Part 2)
Risk factors for a heart attack
* Smoking
* Diabetes
* Aging: 83% of people who die from heart disease are 65 years or more.
* High cholesterol
* Blood Pressure (blood) high
* Family history of heart attack
* Race: African Americans, Mexican Americans, Native Americans and Native Hawaiians are at greater risk.
* Atherosclerosis or hardening of the arteries.
* Lack of exercise
* Stress
* Obesity
* Gender: More men have heart attacks, although heart disease is the leading cause of death among American women.
How I can avoid having a heart attack?
Talk to your family doctor about your specific risk factors (see box above) to a heart attack and how to reduce your risk. Your doctor can say:
* Stop smoking. Your doctor can help. If you do not smoke do not start smoking.
* Eat a healthy diet. Cut back on foods high in saturated fat and sodium (salt) in order to lower cholesterol and blood pressure. Ask your doctor how to start eating a healthy diet.
Warning Signs and Prevention to Heart Attack (Part 1)
A heart attack (also called myocardial infarction) is when part of the heart muscle is damaged or dies because he is not receiving oxygen. The arteries (blood vessels) carry oxygen to the heart.
Most heart attacks are caused by a blockage in these arteries. Usually the blockage is caused by atherosclerosis, which is the accumulation of fatty deposits (called plaque) inside the artery.This buildup is like the gunk that builds up inside a drainpipe and slows the flow of water.
Heart attacks can also be caused by a blood clot that gets stuck in a narrow part of an artery to the heart. Are more likely to form clots at sites where atherosclerosis has made an artery more narrow.
How do I know if I’m having a heart attack?
The pain of a heart attack can feel like heartburn. It is also likely that you are having a heart attack if:
* Feel a pressure or crushing pain in your chest, sometimes accompanied by sweating, nausea or vomiting.
* Feel pain that extends from your chest into the jaw, left arm or left shoulder.
* Has a feeling of tightness in the chest
* Has a shortness of breath for more than a couple of seconds.
Risk Factors and Stroke Prevention (Part 2)
Risk factors that may cause blood more likely to clot, which can lead to stroke include:
* Birth control pills may increase the likelihood of blood clots, especially in women who smoke and are over 35 years
* Disorders of blood clotting
* Cancer
* Rheumatoid arthritis, lupus erythematosus, vasculitis and ulcerative colitis
* Pregnancy: Women have a higher risk of stroke during pregnancy and the weeks immediately after it
Risk factors for strokes caused by blood clots (emboli) that develop in the heart include:
* Infected or artificial heart valves
* Inflammation of the lining of the heart chambers and valves (endocarditis)
* An attack that is not beating strongly or regularly, which can cause blood to remain in the area of the heart, leading to the formation of a clot. The clot can break off and travel to the brain
Risk Factors and Stroke Prevention (Part 1)
A stroke is an interruption of blood supply to any part of the brain, sometimes called “brain attack.”
There are two main types of stroke: ischemic stroke and hemorrhagic stroke.
When a blood vessel supplying the brain becomes blocked by a blood clot, it is called ischemic stroke. The blockage of the artery can happen in two ways.
* You can form a clot in an artery that is already very close and is called a thrombus. If you block the artery completely, is called thrombotic stroke.
* A blood clot may become dislodged from part of the body and travel to the brain to block a smaller artery. This is called an embolism, causing an embolic stroke.
A second major cause of stroke is bleeding in the brain. This is called a hemorrhagic stroke can occur when small blood vessels in the brain become weak and burst.
Some people have defects in blood vessels of the brain that make this more likely. The flow of blood that occurs after the rupture of blood vessels causes damage to neurons.
Men have more strokes than women.
Coronary Artery Disease
Coronari arteries coronary artery disease (CAD) affects almost 13 million Americans, making it the most common type of cardiovascular disease. The CAD and its complications such as arrhythmia, angina and heart attack are the main causes of death in the United States. The most common cause of CAD is a condition called atherosclerosis, which occurs when a waxy substance forms inside the arteries that supply the heart. This substance, called plaque, is made of cholesterol, fatty compounds, calcium and a clotting material called fibrin. Have identified two types of plaque: hard plaque and soft plaque.
Most people have heard of the hard plaque and knows it can cause a heart attack. If hard plaque builds up in arteries supplying the heart, blood flow slows or stops. This decreases the amount of oxygen reaching the heart, which can cause a heart attack.
But it has been determined that although some heart attacks are caused by hard plaque, most of them are caused by the soft plaque or vulnerable plaque. The vulnerable plaque is an inflamed section of an artery that can rupture. This may lead to the formation of a blood clot that can cause a heart attack.
