Primary Coronary Angioplasty —
Emergency Heart Attack Treatment in Hyderabad

Recognising a heart attack — act immediately

Heart attacks do not always present with the dramatic crushing chest pain portrayed in films. Many patients — particularly women, diabetics, and elderly individuals — present with atypical symptoms that are easily dismissed. Any of the following require immediate emergency action:

The 90-minute door-to-balloon target — why it matters

"Door-to-balloon time" (D2B) is the time from a patient arriving at hospital to the moment the blocked artery is opened by the angioplasty balloon. International guidelines set a target of 90 minutes or less — this is the benchmark against which every primary angioplasty programme is measured.

Every 10 minutes of additional delay in D2B time is associated with a measurable increase in mortality. A D2B time above 90 minutes significantly increases the risk of:

• Larger heart attack — more muscle lost, lower ejection fraction
• Cardiogenic shock — the heart too damaged to maintain adequate circulation
• Life-threatening arrhythmias — ventricular fibrillation in the setting of acute ischaemia
• Heart failure — permanent weakness of the heart that can persist for life
• Death

At AIG Hospitals, the primary angioplasty pathway is designed around the 90-minute target. When a STEMI is identified — whether in the emergency department, the ambulance, or the cath lab — the catheterisation laboratory team is activated immediately. Dr. Bhishma Chowdary and the on-call team are available 24 hours a day, 365 days a year.

How is primary angioplasty performed? Step by step

On arrival at AIG Hospitals

1. A 12-lead ECG is performed within 10 minutes of arrival — this is the single most important test to diagnose STEMI. A characteristic ST elevation pattern confirms the diagnosis immediately.
2. Blood is drawn simultaneously for troponin, full blood count, renal function, clotting, and group and screen.
3. Aspirin 300 mg and a loading dose of a second antiplatelet agent (ticagrelor or clopidogrel) are given immediately by mouth.
4. An intravenous cannula is placed. Oxygen, pain relief (morphine or fentanyl), and anticoagulation (heparin) are administered.
5. The cath lab team is activated simultaneously — the patient is transferred directly to the catheterisation laboratory. There is no delay for further investigations if ECG is diagnostic.

In the catheterisation laboratory

6. You are transferred onto the cath lab table. Monitoring leads are attached. Local anaesthesia is injected at the radial artery in the wrist (preferred) or the femoral artery in the groin.
7. A sheath is placed in the artery and a guide catheter is advanced to the opening of the blocked coronary artery under live X-ray guidance.
8. Contrast dye is injected to confirm the location of the blockage. In a STEMI, the culprit artery is typically completely blocked — visible as an abrupt cut-off of dye flow.
9. A fine guidewire is threaded through the clot into the artery beyond the blockage. This is the most critical technical step — crossing the fresh thrombus (clot) in the coronary artery.
10. A thrombus aspiration catheter may be used to remove the soft clot from the artery before ballooning — reducing the risk of distal embolisation (clot fragments travelling downstream).
11. A balloon catheter is inflated at the blockage site — compressing the residual plaque and restoring blood flow. At this moment, most patients notice almost immediate relief of chest pain as circulation returns to the heart muscle. The ECG shows resolution of ST elevation.
12. A drug-eluting stent is deployed at the culprit lesion to maintain the reopened artery and prevent recoil.
13. Final angiography confirms TIMI 3 flow — complete, unobstructed blood flow through the previously blocked artery.
14. If other significant blockages are present in non-culprit arteries, these are usually addressed in a separate planned procedure 1 to 4 weeks later — not in the same emergency sitting, unless the patient is in cardiogenic shock.

Immediately after the procedure

• You are transferred to the cardiac intensive care unit (ICU) or coronary care unit (CCU) for continuous ECG monitoring, haemodynamic assessment, and further medication management.
• Repeat ECG at 30 minutes, 1 hour, and 24 hours confirms the resolution of ST changes and the success of reperfusion.
• Serial troponin measurements track the peak and fall — the peak troponin level correlates with the size of the heart attack.
• An echocardiogram is performed within 24 hours to assess heart muscle function (ejection fraction) and identify any mechanical complications.
• Dr. Bhishma Chowdary reviews the results with you and your family at the bedside — explaining the findings, the procedure performed, and the recovery plan.

Complications of heart attack — what primary angioplasty prevents

The most devastating consequences of untreated or delayed heart attacks are the complications that primary angioplasty specifically prevents by restoring blood flow early:

Heart attack severity — the Killip classification

The Killip classification grades the clinical severity of heart failure at the time of a heart attack — used by cardiologists to assess prognosis and guide treatment intensity:

AIG Hospitals capability for cardiogenic shock

Dr. Bhishma Chowdary has specific expertise in managing Killip Class IV cardiogenic shock — including primary angioplasty combined with Impella support (protected PCI) and ECPella (combined ECMO and Impella) for the most critical cases. This level of MCS capability for acute heart attack is available at AIG Hospitals 24 hours a day.

Recovery after primary angioplasty

In hospital — days 1 to 5

• Continuous ECG monitoring in coronary care unit for the first 24 to 48 hours.
• Echocardiogram on day 1 to assess ejection fraction and wall motion — this establishes the baseline cardiac function after the heart attack.
• Dual antiplatelet therapy (aspirin + ticagrelor or prasugrel) started immediately and continued for 12 months.
• High-intensity statin therapy (rosuvastatin or atorvastatin) started before discharge — LDL target below 55 mg/dL.
• Beta-blocker and ACE inhibitor started when haemodynamically stable — to protect the heart muscle and reduce remodelling.
• Graded mobilisation begins on day 2 — sitting, standing, short walks under supervision.
• Cardiac rehabilitation programme discussed and referral made before discharge.
• Dr. Bhishma Chowdary reviews non-culprit lesions found during emergency angiogram — a planned second procedure for significant remaining blockages is scheduled 2 to 4 weeks after discharge.

At home — the first month

• Rest at home for the first 1 to 2 weeks. Short, flat walks encouraged from day one.
• Avoid driving for 4 weeks after STEMI — confirm timing with Dr. Bhishma Chowdary.
• No heavy lifting, strenuous exertion, or sexual activity for 4 weeks.
• Take all medications without interruption — particularly antiplatelet agents. Never stop without consulting Dr. Bhishma Chowdary. Stopping ticagrelor or clopidogrel early is the most preventable cause of stent thrombosis.
• Attend the 4 to 6 week follow-up appointment — repeat echocardiogram, blood tests, ECG, and medication review.
• Contact AIG Hospitals or present to the nearest emergency department immediately if chest pain recurs, breathlessness worsens, or you feel faint.

Long-term — cardiac rehabilitation and secondary prevention

Surviving a heart attack is not the end of the story — it is the beginning of secondary prevention. The risk of a second heart attack is significantly elevated in the first year, and lifelong risk factor management is as important as the procedure itself:

• Cardiac rehabilitation — a supervised exercise and education programme shown to reduce re-hospitalisation by 30% and mortality by 25%. Strongly recommended for all post-STEMI patients.
• LDL below 55 mg/dL — achieved with high-intensity statin. Add ezetimibe or PCSK9 inhibitor if target not reached.
• Blood pressure below 130/80 mmHg.
• HbA1c below 7% in diabetics.
• Complete, permanent smoking cessation — the single most impactful lifestyle change.
• Mediterranean-pattern diet and regular aerobic exercise — 150 minutes per week once cleared by cardiologist.
• Annual cardiology follow-up for the rest of life — including echocardiogram to track ejection fraction recovery.

Frequently asked questions

What is the difference between a regular heart attack and a massive heart attack?

In clinical terms, all heart attacks involve blockage of a coronary artery and death of heart muscle. The size of the heart attack depends on which artery is blocked and for how long. A blockage in the left anterior descending artery (LAD) — which supplies the front wall of the heart — tends to produce larger heart attacks than blockages in smaller side branches. "Massive" or "widow maker" heart attacks typically refer to proximal LAD occlusions that cut off blood supply to a large area of muscle. With rapid primary angioplasty, even large heart attacks can have good outcomes if the artery is opened quickly.

Can primary angioplasty be done at any time of day or night?

Yes. AIG Hospitals operates a 24-hour primary angioplasty service — 365 days a year. Dr. Bhishma Chowdary and the on-call cath lab team are available at any hour. Heart attacks do not respect working hours — and neither does the primary PCI programme at AIG Hospitals. If you or a family member develops symptoms in the middle of the night, call +91-9000352998 immediately.

What if I have had a bypass operation in the past — can I still have primary angioplasty?

Yes. Patients with prior coronary bypass surgery (CABG) can develop heart attacks — either from new disease in the native coronary arteries or from blockage of a bypass graft. Primary angioplasty can be performed on the native coronary artery or the affected graft depending on which vessel is responsible. Angiography immediately identifies the culprit vessel and the appropriate treatment is undertaken. Prior bypass surgery increases procedural complexity but does not prevent primary PCI.

Will I need another procedure after primary angioplasty?

Possibly. During the emergency angiogram, blockages in other coronary arteries (non-culprit vessels) are often identified. These are not treated during the primary PCI — only the artery causing the heart attack is stented in the emergency setting. Remaining significant blockages are assessed at a follow-up angiogram 2 to 4 weeks later, and further angioplasty (staged PCI) is performed if indicated. Dr. Bhishma Chowdary will discuss the complete angiogram findings with you before discharge and outline the plan for any additional procedures.

How will I know if my heart function is permanently affected?

An echocardiogram performed on day 1 after primary angioplasty shows which areas of heart muscle have been affected and gives an initial ejection fraction reading. This is repeated at 6 to 12 weeks — by which time hibernating muscle that has recovered blood supply often shows improved function. The final ejection fraction at 3 to 6 months determines whether additional treatments (such as a defibrillator device for EF below 35%) are needed. Many patients treated early with successful primary angioplasty recover close to normal heart function.

I was told to take thrombolysis (clot-busting injection) at another hospital — is primary angioplasty still needed?

If thrombolysis (streptokinase or tenecteplase) was given at another hospital, the decision about whether to transfer for primary angioplasty at AIG Hospitals depends on whether reperfusion was successful. Signs of failed thrombolysis — persistent chest pain, persistent ST elevation 90 minutes after the injection — indicate that the artery has not reopened and urgent rescue angioplasty is needed. Even successful thrombolysis is followed by a pharmacoinvasive strategy — coronary angiogram and angioplasty within 3 to 24 hours. Dr. Bhishma Chowdary accepts transfers from other hospitals for rescue and pharmacoinvasive PCI — call +91-9000352998 for direct physician-to-physician discussion.

Can heart attacks be completely prevented in someone who has already had one?

Not completely — but the risk can be dramatically reduced. After a first heart attack, the risk of a second is significantly elevated, particularly in the first 12 months. However, patients who achieve LDL below 55 mg/dL, maintain blood pressure below 130/80, keep HbA1c below 7%, stop smoking completely, take all prescribed medications without interruption, and attend cardiac rehabilitation reduce their 5-year recurrence risk by 50 to 60% compared to those who do not. The investment in secondary prevention after a heart attack is among the highest-return actions in all of medicine.
