How would a blockage in one of the coronary arteries affect the hearts stroke volume?

How would a blockage in one of the coronary arteries affect the hearts stroke volume?

By decreasing oxygen: The heart muscle depends on oxygen supplied by the coronary arteries to effectively function. When the artery is narrowed it can decrease the supply of oxygen and decrease the force of the muscle contraction. The stroke volume is a measure of how much blood the heart forces out with each beat. ...Read more

Can cardiac ablation for atrial fibrillation cause damage to the coronary arteries close to the ablation site

Can cardiac ablation for atrial fibrillation cause damage to the coronary arteries close to the ablation site

Yes but it's rare: The coronary arteries, most specifically a branch of the left circumflex artery run directly beneath a structure called the left atrial appendage. Ablation in that region, or just behind it puts rf energy near that artery. However, the artery has very high flow (relatively speaking) and is thus protected from damage the majority of the time. ...Read more

In what way damage to the conduction system of the heart impact stroke volume?

In what way damage to the conduction system of the heart impact stroke volume?

Lower stroke volume: If part of your heart are not properly innervated, the muscle will not contract as needed and the stroke volume may diminish. Uneven contraction may lead to thrombus formation and potentially stroke, check with your cardiologist. ...Read more

Can you please explain the function of the coronary artery?

Can you please explain the function of the coronary artery?

Blood to the heart: The coronary arteries supply blood to the heart muscle. These are the same arteries that get blocked/clogged by cholesterol and plaque which can lead to a heart attack. ...Read more

What exactly is the circulation path from heart to kidneys to heart?

What exactly is the circulation path from heart to kidneys to heart?

Many finite loops: Left ventricle --> ascending aorta -> descending aorta --> renal artery --> segmental -> lobar a/interlobar a -->arcuate a-->interlobular a->afferent arteriole --> efferent arteriole-->interlobular, arcuate, interlobar veins-> renal vein-> inferior vena cava --> right atrium -> right ventricle -> pulm artery (branches) -> pulm veins -> left atrium -> left ventricle. ...Read more

How to open blockage in heart?

How to open blockage in heart?

Balloons or stents: When needed (blockages >75-80% of lumen of coronary arteries) they can be opened with balloons (angioplasty) or "scafolds" inside the vessels called stents. At age 16 you should not be worried about blockages and the best thing you can do to prevent them is: do not smoke and live a healthy lifestyle with plenty of exercise and avoid being overweight ...Read more

What occurs in the heart to compensate for ischemia?

Vasodilitation: The physiological response to ischemia is for the coronary arteries to dilate. ...Read more

How to deminish fluid in the lungs due to congestive heart failure?

How to deminish fluid in the lungs due to congestive heart failure?

Why do you have CHF?: The answer in part requires your health care provider to determine why you have congestive heart failure and ruling out other possible causes for the fluid, and what other conditions you may have. Among the many important issues: do you have high blood pressure? Any lung disease? Kidney disease? A history of a past heart attack? What's your age? Has treatment been tried before? Did it work? ...Read more

Is pulmonary embolism an obstruction in the main artery to the lung?

Is pulmonary embolism an obstruction in the main artery to the lung?

Any artery: A pulmonary embolism (pe) is a clot in any of the arteries in the lungs. If the clot is large, it will lodge in one of the larger arteries, and can be fatal. If the clot is smaller, it will travel into the lung until the vessel is small enough to trap it, and may not even cause much in the way of symptoms. Any pe is serious, and the source of the clot needs to be found to prevent recurrences. ...Read more

Can a renal artery blockage cause blockages in the legs?

Can a renal artery blockage cause blockages in the legs?

No: No. However, disease that caused renal artery block can cause similar blocks in other blood vessels. Common causes- atherosclerotic disease due to high cholesterol. In young- disorders of vessel walls- fibrous muscular dysplasia. ...Read more

Can you explain the metabolic mechanisms that take place during coronary artery blockage?

Can you explain the metabolic mechanisms that take place during coronary artery blockage?

Yes: A coronary artery blockage of myocardial infarction (heart attack) occurs when an atherosclerotic plaque ruptures losing its fibrous cap and lipid core thereby exposing type-4 collagen which is very prothrombotic (clot promoting). It is the blood clot forming at the ruptured plaque that shuts down the coronary artery. ...Read more

Can you see the carotid and coronary arteries echocardiogram?

Can you see the carotid and coronary arteries echocardiogram?

Not really.: The carotids may sometimes be able to be seen with a transesophageal echo. The coronaries may occasionally be seen, but not to the point of being able to do any sort of diagnosis. ...Read more
