Indications and Candidates for Stent Implantation
Percutaneous coronary intervention is effective in treating heart attacks and other certain cardiac events but not all of them. It is just not considered a “cure-all” option for vascular stenosis or a non-questionably “better” alternative for CAD management. Stents are also used in other vascular narrowing conditions other than coronary artery diseases. We will discuss the most common indications for stent implantation.
1) STEMI (ST-Elevation Myocardial Infarction)
Is a serious medical condition caused by a severe shortage of the cardiac blood supply. Inadequacy of the blood supply for the exerted effort of the pumping heart muscle is usually expressed on ECG as elevated ST segment. Myocardial infarction (MI) which is also known as heart attack is the event in which cardiac tissues are beginning to die as a result of a lack of oxygen and nutrients. Myocardial infarction (MI) is usually developed gradually due to a sedentary lifestyle and unhealthy diet. The most typical presentation of MI is chest pain radiating to the left shoulder, neck, and jaw that exacerbates with physical effort and is relieved with rest.
it is believed that Primary percutaneous coronary intervention (PPCI) with stenting has become the gold standard revascularization approach for the treatment of ST-segment elevation myocardial infarction (STEMI) as it outperforms thrombolysis (breaking down blood clots) or balloon PCI alone. Cardiac tissues are sensitive to a lack of oxygen and can’t tolerate a lack of blood supply for a long period. Therefore, immediate medical intervention is always the key to avoiding irreversible damage to heart muscles. In case of complete coronary occlusion, the supplied muscular tissue will spontaneously start to infarct (die) after half 30 minutes.
