A stent is a small mesh tube inserted into a narrowed coronary artery during angioplasty to restore blood flow and prevent heart muscle damage. It details when doctors may consider stenting—such as in cases of severe artery constriction, angina unresponsive to medication, ongoing heart attack, or high risk of a repeat cardiac event.
Key warning signs prompting evaluation include persistent chest pressure, breathlessness during mild exertion, unexplained fatigue or light-headedness, and classic heart attack symptoms like jaw or arm pain, sweating, and nausea.
Diagnostic tests such as ECG, echocardiogram, stress tests, and especially coronary angiography help confirm the need for the procedure.
Understand alternatives when stenting may not be ideal—such as mild narrowing manageable with medication or bypass surgery—and highlights different stent types like bare-metal, drug-eluting, and bioabsorbable scaffolds. It emphasizes that long-term success depends on medication adherence, lifestyle changes, and regular follow-up.
