Most people first hear the word angioplasty in a cardiologist's room, usually after a stress test or CT scan has shown something the doctor does not like. The conversation that follows can move quickly, and patients often leave with a procedure date before they fully understand what is being proposed. A little background makes that conversation easier.

What does angioplasty actually do?

Coronary angioplasty, medically known as percutaneous coronary intervention or PCI, opens a narrowed or blocked artery that supplies the heart muscle. A thin catheter is passed through an artery in the wrist or groin up to the heart. A small balloon is guided to the narrowed part of the artery and inflated to improve blood flow.

In most cases, a mesh stent is then placed to keep the artery open. Most stents used today are drug-eluting, meaning they slowly release a medicine that reduces the chance of the artery narrowing again.

Who needs angioplasty?

Angioplasty may be recommended when a coronary artery is significantly narrowed or blocked. It is often performed urgently during a heart attack to reopen the artery and restore blood flow to the heart. For stable angina, treatment depends on the severity of the blockage, symptoms and test results. Some patients can manage their symptoms with medicines, while others may need bypass surgery. Your cardiologist will assess your condition and discuss the most suitable treatment.

Before the angioplasty procedure

Before coronary angiography, you may have blood tests to check kidney function, as the contrast dye is removed from the body through the kidneys. Your doctor will also review your regular medicines. Some blood thinners and diabetes medicines may need to be adjusted before the procedure, and an antiplatelet medicine may be prescribed. Tell your medical team if you have had a reaction to contrast dye or iodine. You will usually need to avoid food and drink for a few hours before the procedure.

In Dubai, planned procedures generally need insurance pre-approval, so ask the hospital to start that process early. It avoids last-minute delays on the day.

In the cath lab

Most patients remain awake during the procedure. The doctor numbs the access site with a local anaesthetic, and a mild sedative may be given to help you relax. In a catheterisation lab, the catheter is often inserted through an artery in the wrist, although the groin may also be used.

The doctor first takes images of the coronary arteries. If a significant blockage is found, angioplasty and stent placement may be carried out during the same procedure. Some patients feel brief chest discomfort when the balloon is inflated. A routine procedure may take less than an hour, while complex blockages can take longer.

Risks worth understanding

Angioplasty is a common procedure, but it still carries some risks. Bruising or bleeding at the catheter insertion site are among the more common problems. Other possible complications include artery damage, a reaction to the contrast dye and changes in kidney function. Heart attack or stroke can occur during the procedure, although these complications are uncommon. Your doctor can explain your individual risk, particularly if you have kidney disease or diabetes.

Questions to ask

• Why angioplasty rather than medicines or bypass?

• How many arteries are involved?

• Which access route will you use?

• How long will I need antiplatelet medicines?

• Whom do I call if something feels wrong after I go home?

Choosing the Best Hospital for Angioplasty and Coronary Stenting

Patients searching for the best angioplasty and stenting hospital in Dubai are usually weighing reputation, but the practical questions are more telling. Does the hospital run a cath lab around the clock, not just in office hours? Does it handle complex disease, such as long-standing total blockages or heavily calcified arteries? And is cardiac surgery available on site if the plan needs to change?

The same questions are worth asking of any hospital described as the best cardiology hospital in Dubai: which procedures does it perform routinely, and who performs them?

Where is angioplasty available in Dubai?

A significant number of patients visit Aster Hospitals, in their multiple locations in Dubai, including Aster Cedars Hospital in Jebel Ali and Aster Hospitals in Mankhool, Muhaisnah and Al Qusais. Its cardiology department performs coronary angiography in a cardiac catheterisation lab, angioplasty with stenting, chronic total occlusion (CTO) interventions for long-standing blockages and atherectomy, which shaves hardened calcium from inside the artery. Bypass surgery is available in the same department, which matters when angiography shows that surgery is the better option.

Whatever hospital you choose, go in understanding why the procedure is being done. That knowledge tends to make the recovery that follows smoother too.
