If healthcare providers (HCPs) see a narrowed heart vessel while performing a percutaneous coronary intervention (PCI), they may perform a balloon angioplasty to compress the plaque against the vessel wall and hold it there with a stent, which will lessen dropdownanddropdown.

Pain from myocardial ischemia occurs when narrowed coronary arteries restrict blood flow to the heart muscle. PCI with balloon angioplasty and stent placement reopens the blocked artery, restoring oxygen-rich blood and thereby relieving ischemic chest pain symptoms that were previously unrelieved by rest. Dysrhythmias often develop as a result of decreased perfusion to the heart’s conduction system during ischemia. By improving blood flow through PCI, the myocardium becomes more electrically stable, reducing the risk of ventricular or atrial dysrhythmias related to oxygen deprivation and myocardial irritability. Heart blocks occur when electrical conduction through the heart is delayed or interrupted, often due to damage in the conduction pathways. PCI does not reverse scarring or fibrosis of these pathways and is not a treatment for conduction system abnormalities like AV block unless directly caused by ischemia. Palpitations are often caused by a range of factors including anxiety, stimulants, or electrolyte imbalances, in addition to arrhythmias. While some ischemic-related arrhythmias may improve after PCI, palpitations due to non-cardiac or unrelated causes would likely persist despite successful revascularization. Shortness of breath can be due to myocardial ischemia, but also stems from pulmonary conditions or left-sided heart failure. Although PCI improves cardiac perfusion, it does not directly resolve fluid overload or pulmonary congestion, which may still contribute to dyspnea even after the intervention.
