Lowering LDL cholesterol prevent heart attacks and strokes

Lowering LDL cholesterol is currently one of the primary public health initiatives preventing atherosclerosis and heart attacks. The benefits of lowering LDL cholesterol are:

Reducing or stopping the formation of new cholesterol plaques on the artery walls
Reducing existing cholesterol plaques on the artery walls and widening the arteries
Preventing the rupture of cholesterol plaques, which initiates blood clot formation and blocks blood vessels
Decreasing the risk of heart attacks
Decreasing the risk of strokes
Decreasing the risk of peripheral artery disease

The same measures that decrease narrowing in coronary arteries also may benefit the carotid and cerebral arteries (arteries that deliver blood to the brain) as well as the femoral arteries that supplies blood to the legs.






Links of HYPERTENSION, the Silent Killer

Experts know that many different factors are linked to high blood pressure. But experts still don’t fully understand the exact cause. Factors that are linked to high blood pressure include:
Aging.
Drinking more than 2 alcoholic drinks a day for men or more than 1 alcoholic drink a day for women.
• Eating a lot of sodium (salt).
• Being overweight or obese.
Not exercising.
• Being under a lot of stress.
• Eating a diet low in potassium, magnesium, and calcium.
• Being insulin-resistant.
Primary, or essential, high blood pressure is the most common type of high blood pressure. Most people who have high blood pressure have primary high blood pressure.
Secondary high blood pressure, which is caused by another disease or medicine, is less common.
Elevated blood pressure readings may not always mean that you have high blood pressure. For some people, just being in a medical setting causes their blood pressure to rise. This is called white-coat hypertension.






Can SEX trigger HEART ATTACKS?

-Sex and exercise can trigger heart attacks in older people who don’t get much of either, a new analysis has found.

-The risk is low, but it’s a good reminder that slackers should change their exercise habits gradually, especially in middle age. People who exercise regularly have a much smaller risk of having a heart attack immediately after sexual or physical activity, said lead author Dr Issa Dahabreh of Tufts Medical Center in Boston. “It would be really bad if someone thought our paper means people should not exercise,” Dahabreh said. “If anything, it’s the opposite.”

-The analysis, which appears in the Journal of the American Medical Association, combined results from 14 studies involving more than 6000 patients. The studies involved only people who had had heart attacks or who had died suddenly of a heart problem.

Let’s watch a video about EECP, procedure that’s also helps in heart attack prevention and sex activity:






Elderly DEPRESSION linked to DEMENTIA risk

-Seniors with depression may have a higher risk of mild cognitive impairment (MCI) and dementia, researchers from University of Amsterdam, the Netherlands, reported in Archives of Neurology, Online First.

-The authors had gathered and examined data on a group of Medicare recipients in the USA who were 65 or over.

-According to the researchers, studies have indicated that from 3% to 63% of patients with MCI have depressive symptoms. Other studies have demonstrated that people with a history of depression have a higher risk of dementia during their later years. A study published in Archives of Neurology revealed that mild cognitive impairment and dementia are much more common among very old women.






ULTRASOUND to PREVENT STROKE?

-Scientists may have discovered a new way to prevent strokes in high risk patients, according to research from the University of Warwick and University Hospitals Coventry and Warwickshire (UHCW).

Work by a new research group, led by Professor Donald Singer, Professor of Therapeutics at Warwick Medical School and Professor Chris Imray from UHCW, has now been published in US journal Stroke.

-The group is using ultrasound scanning to look at patients with carotid artery disease, one of the major causes of stroke. Clots can form on diseased carotid arteries in the neck. Small parts of these clots can released to form microemboli, which can travel to block key brain arteries and lead to weakness, disturbed speech, loss of vision and other serious stroke syndromes. Standard anti-platelet drugs such as aspirin may not prevent the formation of harmful microemboli.

-The scanning process can be used to find patients at very high risk of stroke because microemboli have formed despite prior anti-platelet drugs. Using scanning, the team has found that tirofiban, another anti-platelet drug designed to inhibit the formation of blood clots, can suppress microemboli where previous treatment such as aspirin has been ineffective. In their study, tirofiban was more effective than other ‘rescue’ treatment.
