Not usually. A heart attack occurs when there is sustained insufficient blood supply to the heart to meet the heart's metabolic demand. If you lose a lot of blood and your heart already has a compromised supply you can have a "heart attack" most typically heart attacks are caused by progressive or acute plugging of one of the arteries of the heart with plaque and clot.
Vitamink. No, vitamin k wil not thicken the blood to cause blockage and a heart attack.
No. It does impact persons on Coumadin (warfarin) and reverse that anticoagulation if indicated, to reverse due to bleeding or need surgery. Enhanced clotting can happen.
What causes heart attacks that have completely normal blood pressure levels and normal cholesterol levels? What is the rate of occurence
Heart attack. Heart attack is typically caused by a heart blood vessel blocking off. The usual disease causing this is called atherosclerosis and is related to blood pressure, blood fats, diabetes, smoking, lack of exercise, stress and other factors. We treat heart attack patients for life with aspirin, beta blockers, ace inhibitors and other medications sometimes. We also do procedures sometimes to open vessel.
Not the main. Hypertension causes left ventricular hypertrophy and strain and heart failure. Concomitant coronary disease can occur and infarction can happen hypertension is also asso. With aortic tear-dissection and that can involve coronaries and cause infarction. More to the entire story but that' s a start.
Atherosclerosis. Hypertension is a major cause of atherosclerosis which may cause heart attacks.
May not. Many people with high BP do not have heart attacks. The heart is strained and hypertrophied, and in the presence of atherosclerosis may have obstruction and dissection, or plaque disruption to create a heart attack.
Yes. High blood pressure along with high cholesterol, smoking, diabetes, family history all contribute to the development of atherosclerosis. It is the rupture of these plaques in coronary arteries that causes heart attacks. It takes years to develop significant atherosclerotic plaques.
Impossible to answer. Believe it or not, htn, while a risk factor, is a relatively weak risk factor for heart attack. It's a big risk factor for stroke and congestive heart failure. (also kidney failure). Generally, risk factors must be present for decades to cause a heart attack, thus the "coronary prone age" is usually considered to be >55 for men and >65 for women (with many younger exceptions!).
Years. High blood pressure contributes to the formation of atherosclerotic plaques in coronary arteries. This process takes years to develop.
