What causes a heart attack and stroke

A specialized medical journal of the United States, entitled "Clinical Cardiology", recently published a new study about the cause of heart attack and stroke.

Results of the study showed that the crystalline cholesterol buildup of plaque inside blood vessels as the culprit causing this illness.

Previously, scientists said that when the plaques in blood vessels rupture and cause blockage often causes heart attacks and strokes.

Professor Gioocgio S. Abela at the University of Michigan said when cholesterol crystallizes, two phenomena can occur: first, if a large "pool" cholesterol liquid, it will spread out and puncture the walls of blood vessels; second, if a crystal sharp as needle-like structure, it will break through into the same circuit as the nails into the wood.

According to Prof. Abela, ever, in the process of treating and preventing heart disease and stroke, the medical community is not paying attention to the process of cholesterol crystals.

With this new discovery, the researchers hope to find new treatments, more effective for this disease.

Heart attack - causes unexpected

When it comes to heart disease, people usually think of diet and lifestyle, but there are also reasons that you would never think that it is likely to be harmful to the heart.

Where you live. A study of heart attack in the last 9 years in those aged 45-64 years showed that people in low-income neighborhoods has increased to three times the chance of getting heart disease than peers with similar income education and work but live in high-income residential areas.

Antibiotics. Antibiotic azithromycin has a high risk of death in people with heart disease.

Calcium supplementation. A recent study in the journal Heart made in 23,000 people found that those eating calcium supplement on the road at risk of heart attack than others.

Infection. If you are diagnosed with the flu or a respiratory infection, the risk of you having a heart attack is five times higher. When an infection causes inflammation, trigger a heart attack or stroke.

Psoriasis. Psoriasis is a cause of heart level with diabetes.

The relationship is not good. The bad relationship can cause damage to the heart both literally and figuratively. According to a study by the Institute of Epidemiology at the University of London, bad relationships can increase 34% the risk of heart disease.

Low good cholesterol. A study of nearly 7,000 people by a researcher at the University of Indiana (USA) analyzed the relationship between cholesterol and coronary heart disease. The study concluded that low cholesterol is the third largest cause of coronary artery disease after heart disease and age.

Kidney problems. A study of elderly patients in Rotterdam in the Netherlands found that those with weak kidneys also are at high risk of heart attack. Another study conducted in 10,000 men found that those with chronic kidney disease will be 2 times the risk of heart attack compared to those without kidney disease.

Urban living. According to a study by German scientists, whether you are traveling by car, bike, or public transportation can double the risk of heart attack. A previous study also found that deaths from heart disease, lung mostly people who live near major roads.

Exercise helps prevent heart attacks

Recent U.S. study showed that the risk of a second heart attack reduced 60%  in those who remain active after the first heart attack, compared with those who did not exercise. This is the first works use of a large number of patients to analyze the effects of exercise after a heart attack.

However, according to the cardiologist, exercise must be consistent with the patient's health status as well as the severity of the heart attack, in order to avoid overloading the heart. The slow movement, but the long form such as walking, cycling are important because they reduce the levels of cholesterol and lipids. In addition, the exercise strengthens the upper part of the body is also essential, because the operation of the arms and upper body often causes fatigue to heart so much.

In addition to preventing heart attack, exercise is also an effective remedy for many diseases. Previous studies have shown that the performance usually adjust better, thinking more clearly, less heart disease related to stress, less anxiety or depression.

Handling of heart when it comes to the emergency

Heart attack is one of the leading causes of death in the world. The main reason is because there is no emergency measures timely and appropriate from a heart attack until taken to the hospital.

Here are some guidelines needed to help you cope in this situation:

 - Every minute is very important, so be quick handling. Do not give anything by mouth to patients, even a little better, it should be taken to the nearest hospital as soon as possible. Remember that no one at the appropriate therapy for heart attack patients.

 - Place the patient lie down, loosen clothing and taken to the emergency room immediately. For patients to chew an aspirin and swallowed completely.

 - Set Sorbitrate under the tongue. If there are signs of sweating a lot, such as hypotension,

should not.

 - You can put a teaspoon of powdered glucose constant on or under the tongue. Not a drink

sweet.

- If a person is signs are not aware, should apply cardiopulmonary resuscitation techniques - lungs (CPR: airway, breathed breaths, pressing the sternum to stimulate the heart).

 - Be patient approach to medical equipment as quickly as possible, do not over use the emergency on spot.

 - Anatomy of the secondary circuit is the method gives results immediately after a heart attack within the first 90 minutes.

How to recognize early heart attack
