Angioplasty: Complication Rates and Why Fast Treatment Matters
June 2, 2024
Angioplasty is a very safe procedure by modern standards, but understanding its realistic complication profile helps set expectations.
How safe is angioplasty
PCI is roughly 95 to 98% safe. The complications that can occur include access-site bleeding from the hand or groin, and rarer complications related to the coronary arteries themselves, such as stent thrombosis (a blocked stent) or, in technically difficult vessels, a perforation. Fatality is a rare, extreme-case outcome rather than a typical one.
Why treatment is worth the risk
An untreated heart attack carries a 30 to 50% chance of death. Treating it promptly, whether with PCI or thrombolysis, brings that risk down to around 5%. That gap between untreated and treated outcomes is why acting within the first two hours of a STEMI, in particular, matters so much.

What is the role of cardiac defibrillation?
Dr. Vikas Thakran
During an acute coronary event, external defibrillation is used for life-threatening ventricular tachycardia or ventricular fibrillation, whether at presentation, during the procedure, or post-operatively. On longer-term follow-up, patients with poor heart function (a low ejection fraction) may need an ICD, a device similar to a pacemaker, implanted to protect against these arrhythmias.

Frequently Asked Questions
What are the expected complications of an angioplasty procedure?▼
Angioplasty is roughly 95 to 98% safe. The complications that can occur are access-site bleeding from the hand or groin, and rarer complications related to the coronary arteries themselves, such as stent thrombosis (a blocked stent) or, in difficult vessels, a perforation.
What motivates this line of work?▼
A heart attack patient left untreated has a 30 to 50% chance of dying; treated promptly with a procedure or thrombolysis, that risk falls to around 5%. Saving the largest number of lives in the smallest amount of time, across the globe, is the reason and the motivation.
For a patient with anterior wall MI who has also fainted and is in a critical condition, how do you manage evacuation to an Indian hospital?▼
Jivo's international team manages the entire process end to end, from the visa process to ambulance transfer at the airport, and makes sure family members travelling with the patient are comfortable too. They first take the patient's details and advise on the right course of action, so the point of contact should be the international team, who will coordinate directly with BLK-Max.
How is a PCI (angioplasty) actually performed?▼
Access is gained through either the radial artery in the wrist or the femoral artery in the groin. An angiography is first done through a catheter placed in that artery to locate the blockages, and a treatment plan is formed. A wire is then passed across the blockage, a balloon is used to open it, and a stent is placed. If there are multiple complex blockages that would need too many stents, coronary artery bypass surgery is recommended instead, decided by a heart-team approach. In an acute heart attack, PCI directly clears the thrombus, places a stent, and restores flow.
In terms of statistics, how many heart transplant cases have you handled?▼
The need for heart transplantation has dropped drastically because of the medical and interventional therapies now available. Donor availability and financing also remain real constraints. In practice, the centre performs about two to three transplants a year, though the facility is available for extreme cases when a donor is available.
What are the complications of angioplasty?▼
Access-site bleeding from the hand or groin, and rarer complications such as stent thrombosis or vessel perforation; the procedure is overall 95-98% safe.
How much does treatment improve heart attack survival?▼
An untreated heart attack carries a 30-50% chance of death; prompt treatment with PCI or thrombolysis brings that down to around 5%.
