balloon-tipped catheter through the artery to the blockage. The collapsed stent is part of the catheter tip, and when the balloon is inflated the stent expands into place allowing the flow of blood once again
Patients underwent coronary angiography and continued in the study if they required a coronary stent in the "culprit" lesion. Baseline bloods from aortic root, coronary sinus and systemic venous were taken together with the measurement of the index of microvascular resistance, coronary flow reserve, ...
They slow or stop the progression of coronary heart disease and also deter repeat heart attacks. Clinical trials have shown beneficial effects immediately after a heart attack or threatened heart attack, even before the fat lowering effect is maximal, meaning they stabilize the plaque. Examples ...
The decision to try and stent a coronary artery versus doing bypass surgery is usually recommended to the patient by their cardiologist and a heart surgeon. Bypass surgery is usually done if coronary arteries are narrowed or blocked in multiple places. The procedure is known as coronary artery by...
(ultrasound) to generate images. Echocardiograms use the same noninvasive technology used to examine the fetus during pregnancy. It can show how well heart chambers and heart valves are functioning (for example, effective or poor pumping action, blood flow through the valves), before and after ...
before, during, and after the stress test. The test is 60% to 70% accurate in detecting blocked coronary arteries. Sometimes, a patient may be too weak or deconditioned to perform a stress test. In that case, the doctor can administer medications that simulate the heart activity during ...
Everything that has an advantage must have a disadvantage and same is true with heart stents surgery. Heart stent helps the arteries from blocking but it has its own share of risks, side effects and other problems. Since the stent is made of metal it can cause an allergic reaction to the...

Medical procedures or surgeries, such as heart valve surgery, coronary artery bypass graft surgery, or having a balloon or stent placed Cardiac rehabilitation, which uses a supervised exercise program to help your heart get stronger after after a heart attack, if you have heart failure, or after...
We validated our new technique by i) computational modeling of cardiac ischemia, ii) video recordings of ischemic/reperfused rat hearts, iii) videos of beating human hearts before and after coronary artery bypass graft, and iv) local Frank- Starling effect. In rats, we observed a decrement of...
