A Chinese study (included in the JACC paper) found that folic acid supplements reduced the risk of stroke 22 percent overall and 73 percent in participants who took folic acid in addition to their blood pressure medication. But those findings might be different if a similar study were conducted in the U.S., where cereals, breads, pasta and rice are fortified with folic acid. The Chinese diet is lower in folate than our diet. It is unclear whether additional dietary folate would be beneficial here, says Dr. Hazen.
If you have risk factors for cardiovascular disease, or have been diagnosed with heart or vascular disease, what are you doing to lessen the likelihood you will suffer a heart attack or stroke? Are you eating a heart-healthy diet and exercising? Keeping your blood pressure, blood sugar and cholesterol levels under control? Have you tossed your cigarettes to the curb.
This is a special type of stress test ordered to evaluate heart failure or a potential heart transplant recipient, or to determine whether shortness of breath is caused by heart or lung disease. It is performed on a treadmill or cycle with EKG, but a breathing apparatus is used to measure oxygen use and carbon dioxide production.
Most people know the classic symptoms of heart attack: pain in the left or center of the chest often described as heaviness, tightness or pressure, which can radiate to the jaw or left arm and may be accompanied by shortness of breath, sweating and nausea.
Having an autoimmune disease such as rheumatoid arthritis, psoriasis, ankylosing spondylitis, celiac disease, lupus or inflammatory bowel disease greatly increases the risk of developing cardiovascular disease. The connection is systemic inflammation. Inflammatory cells settle in blood vessel walls, where they perpetuate inflammation and make plaque prone to rupture, causing a heart attack or stroke.
For more than a decade, weve known that the more physically active and fit you are, the lower your risk of developing heart failure with preserved ejection fraction (HFpEF), the type of heart failure most common in women.
When LDL and HDL exist in normal proportion, they are not a health risk. But when levels of LDL or total cholesterol rise, or the amount of HDL falls, the body tends to deposit cholesterol in the arteries. Over time, this causes arteries to become narrow, which can interfere with blood flow and lead to heart attack or stroke.
In a heart attack, minutes count. The faster blood flow is restored to the heart, the better the chance the patient will survive. Now, Cleveland Clinic and other major medical centers nationwide are working with emergency medical services (EMS) to make innovative changes in the way heart attack patients are treated. The result is faster heart-attack care and more patients leaving the hospital alive.
The risk of stroke or heart attack is 5 to 10 percent per year in patients with stable atherosclerosis. Obese patients with type 2 diabetes are at greatly increased risk for heart attack and stroke, largely due to elevated blood glucose, blood pressure and cholesterol levels. In the first study of its kind, stereotactic external beam radiation, a type of radiation therapy used to treat tumors, proved effective in virtually eliminating ventricular tachycardia (VT) in patients who had failed conventional treatment.
If you have stable angina-meaning your chest pain occurs predictably with physical exertion and disappears with rest-your doctor may recommend a percutaneous coronary intervention (PCI, or balloon angioplasty and stenting) to relieve your symptoms.
New research reveals some insight into why some people live long lives with their memory intact. The brain is highly dependent on a steady flow of oxygenated blood. When the heart is unable to meet the brains needs-for example, when heart failure weakens the hearts pumping power-brain function is impaired. What about patients who dont have heart failure?
In a world of increasingly sophisticated tests for heart disease, one golden oldie continues to stand out: electrocardiography. This method of recording the hearts electrical activity was developed in the early 20th century and remains the first test doctors reach for when a patient exhibits the signs or symptoms of heart disease.
