Can Hypertension Cause Atrial Fibrillation
Yes: Atrial fibrillation is an irregularly irregular heart rhythm , it can happen when the atrium( upper chamber of the heart) is enlarged. Hypertension causes the heart to work harder, develops hypertrophy to have enough force to push the blood forward from the ventricle ( lower chamber of the heart); the atrium in turn enlarges to push blood to ventricle and eventually dilates then a-fib develops. ...Read moreSee 1 more doctor answer
A blood pressure reading has two numbers: a systolic blood pressure and a diastolic blood pressure. The systolic blood pressure is the maximum pressure the blood exerts on the vessels when the heart is beating. The diastolic blood pressure is the pressure the blood exerts on the vessels in between heartbeats. Hypertension, or high blood pressure, begins when the systolic blood pressure remains above 140 or when the diastolic blood pressure remains above 90. Hypertension can be a result of increased blood flow through vessels or increased resistance to ...Read more
Which is better and more safe in general for treating hypertension and atrial fibrillation metoprolol succinate or bisoprololesp. If s.creatinine1.56
Neither. In clinical: trials, carvedilol has significantly better outcomes than either metoprolol (e.g. 3%/yr lower mortality rates continuing for many years) or bisoprolol. Creatinine is quite another issue, produced by all muscle cells, yet used to crudely estimate renal filtering function, not the 4 known responses to carvedilol. Yet the clinical trial data for all the Beta blockers is as augmenters to ACEI agents. ...Read more
What is the safest anticoagulant to be used in 72 yr patient with paroxysmal atrial fibrillation and hypertension?
Anticoagulation: Your doctor needs to evaluate the situation and pick an agent that is the best for the individual situation. There are many factors to be considered and a one size fits all recommendation is not in general appropriate. ...Read more
2 mechanisms : First - high blood pressure increases the pressures in your heart and left atrium which triggers the pulmonary veins to fire and send out electrical signals that can short circuit the heart. Second - long standing hypertension dilates the atria and causes fibrosis which makes it easier to short circuit those chambers and stay in atrial fibrillation. ...Read moreSee 1 more doctor answer
What issues could there be with my thyroid profile given that I suffer from high blood pressure and atrial fibrillation?
?hyperthyroidism: Both hyperthyroidism and hypothyroidism produce changes in cardiac contractility, myocardial oxygen consumption, cardiac output, blood pressure, systemic vascular resistance.Well known that hyperthyroidism can produce atrial fibrillation,less well recognized that hypothyroidism can predispose to ventricular dysrhythmias.In almost all cases cardiovascular changes reversed by thyroid hormone therap ...Read moreSee 1 more doctor answer
Could you tell me if person has atrial fibrillation, is taking metoprolol , Valium as needed .Also now require second medication for high blood pressure which one can go with Valium above.
Grandmother has atrial fibrillation am i at increased risk? I have sinus tachycardia and high blood pressure
Tough call: You're asking a good question that's hard to answer. 3 million people in the us have atrial fibrillation, and of those, ~30% have at least 1 family member with afib. But because there's so much afib out there, and because the prevalence is so high in advanced age (8% at 80yrs, 16%+ at 90) it's hard to decide what the specific risk due to any given family member is. ...Read moreSee 1 more doctor answer
Atrial fibrillation + high blood pressure 141/87. On 4mg warfarin INR 3 / 5mg amlodipine 5mg bisoprolol for 3months. Why isnt BP going down.What risks?
Compensation: Sometimes when you start BP meds, the kidneys compensate in an attempt to maintain the (too high) BP. Add a mild diuretic like hydrochlorothiazide 25 mg (cheap as water, gentle, you won't even know you're taking it) and I'll bet you'll see your BP fall nicely. Your INR is perfect! ...Read more
What are the causes of atrial fibrillation and can it be transient. I am a 60 yr old male with treated hypertension and elevated cholesterol.?
We don't really know: Af can be due to normal wear and tear as occurs in HTN and the aging process. Aging causes insertion of non-conducting tissue (scar) between normal heart cells which is bad. All old people get this but not all old people get af. Why? We know that nests of cells fire crazily at times triggering af. These nests are frequently located in pulmonary veins. But why, and what triggers them? ...Read moreSee 1 more doctor answer
Atrial fibrillation: Atrial fibrillation , or afib, is a very common rhythm disturbance, the most common in this country. It is most often associated with hypertension, but can also be associated with valvular disease specifically mitral valve disease. It can be treated with either rate control or converting back to the normal sinus rhythm. Patient are often placed on blood thinners to prevent complications. ...Read moreSee 1 more doctor answer
Clot formation: Because blood in the left atrium is not propelled forward normally during atiral fibrillation, it allows for the formation of clots. Small areas of blood pooling resembling little eddy currents allow blood to slow down and form clots. If one of these clots is then propelled forward it can travel to the brain, become lodged in a blood vessel and cause a stroke.A clot the size of a pinhead can do it. ...Read moreSee 1 more doctor answer
Standstill: The extremely rapid rates of atrial fibrillation are in fact so fast that they create two problems: the top chamber is not mechanically moving very far at all, so it cannot shake clots loose, and the overactive atrial tissue secretes chemicals which increase the likelihood of clot formation. These processes come together to substantially increase stroke risk. ...Read moreSee 1 more doctor answer
Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more
Only in a Very Few: Generally, the answer to this is a very solid "no." this is a rare complication of people with another condition (on top of their afib) called wolff-parkinson-white syndrome (or wpw). In certain patients having both conditions, the top chamber is too-well connected to the bottom and can trigger ventricular fibrillation. ...Read moreSee 1 more doctor answer
Why the atrial fibrillation causing thromboembolic phenomena while atrial flutter don't cause it?
Short answer: Atrial fib has increased risk secondary to irreg.firing of atria and valves causing damage to blood cells. In flutter there is a more regular rate and atrial contractile function offers some protection but there is still a slightly increased risk. In chronic flutter, coagulation is necessary given the risk of stroke is the same as atrial fib. Pts with chronic flutter often have a fib as well. ...Read moreSee 2 more doctor answers
