Why Do People With Artificial Heart Valves Have To Take Blood Thinners
Risk x clots: Artificial valves statistically are more prone to cause clots. Red blood cells crash against their hard surfaces triggering the cascade for clotting. This does not occur with bio prosthetic valves made of animals like pigs, or cadaver duramadre( meningeal layer). ...Read moreSee 1 more doctor answer
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
Why do patients have to take anticoagulants when they receive and artificial valve in their heart?
Risk vs benefit: In life (& in medicine), everything we do is a balance of what benefit we hope to gain vs. what risk we have to take. The correct treatment for someone who has had a heart attack or stroke (in the long term) is aspirin. That comes with a small risk of bleeding. Coated aspirin, especially the 81 mg strength) is unlikely to aggravate gastritis or stomach ulcer since it dissolves lower down. ...Read more

If someone gets high blood pressure, are they stuck with it for life (like diabetes )? Why does BP tend to increase with age ?
great question: BP does tend to increase with age. If i could answer why, there would be a nobel prize waiting for me! if you're overweight or salt your food, you may be able to reverse it by losing weight and avoiding salt. Otherwise, you'll need medicine. The good news: outcome studies show that when BP is well controlled, you lower your risk of heart failure, heart attack, stroke, kidney failure, and death. ...Read more
Can echos show pulmonary hypertension if you don't have it just because your body is full with fluid? I have polydipsia & changing pulmonary pressures
Interesting question: Elevation of pulmonary pressures can result from volume overload, particularly when there is left heart failure. A normal right heart, however, can compensate for increased volume for a period, preventing increases in pressure. When persistent stresses lead to structural changes in the cells of the right heart, it cannot compensate further and increased pressure results and by echo indices of PHT ...Read more
Why do nsaids pose such a high risk for heart disease? I was prescribed blood thinners to prevent stroke and heart attacks

Complicated: By lack of exercise, do you mean complete immobility? Also, what type of diet is the person consuming? Are they under a lot of stress? What is the family history? Many things contribute to good heart health. Exercise is but one of them, constant low intensity activity without exercise can still keep someone's heart healthy with the right diet and well managed stress and sleep. ...Read more
Ways to reduce cholesterol? Generally healthy, and not overweight but have high cholesterol. Also have slight sinus bradycardia/sinus arrhythmia. Doctors have told me not to worry after repeated EKGs. I want to keep my heart healthy/avoid CHF later?
Mostly genetic: A very high cholesterol may need to be medicated now, if for example you have familial hypercholesterolemia with LDL over 200. It is fairly common and deadly. Exercise is actually more helpful than diet here and you want to maintain lifelong good habits. There are guidelines, and there's no reason to believe super-tight cholesterol control in youth benefits you decades later. ...Read moreSee 1 more doctor answer

Can you let me know how many strokes/heart attacks happen in people with normal cholesterol and blood pressure levels?
Stroke MI: Great question! myocardial infarction in individuals with no cholesterol, blood pressure, smoking, diabetes, or obesity is very rare but can happen. Stroke on the other hand is not uncommonly associated with blood cloths caused by certain heart rhythm abnormalities such as atrial fibrillation. ...Read moreSee 1 more doctor answer
Looking for opinions about people who have had broken heart syndrome, should they stay on beta blockers or not and why?
I have Afib. I read that 1 out of 3 people with Afib will have a stroke. Is that true even if I'm treated with Warfarin and rhythm medications?
Atrial fib & stroke: There are a few guidelines that can be used to estimate the risk of stroke in a patient with atrial fibrillation. One of the best is the "CHA2DS2-VASc" score. If the risk of stroke is high, anticoagulation with warfarin or one of the newer oral anticoagulant meds is usually advised. Antiarrhythmic drugs may reduce episodes of atrial fibrillation, but won't eliminate the risk of stroke. ...Read more
Agents which slow ;/or break down blood clot formation in up to 3 different ways (they do not decrease blood viscosity; thickness.) (1) some inhibit platelet function (e.g. Aspirin, clopidogrel, etc.). (2) others interfere with some of the clot forming proteins (warfarin, dabigatran, rivaroxaban, etc.), (3) others stimulate the blood clot destruction ...Read more
