Coronary Artery Bypass Graft (CABG) in India

The M-category medical visa requires a letter from the treating Indian hospital confirming the appointment and nature of treatment, along with a standard visa application. It can be obtained for stays of up to sixty days, extendable within India, and includes a companion (attendant) visa for an accompanying family member or carer. Applications are made through the Indian embassy or high commission in the patient's home country.

India uses the Indian Rupee (INR). Major international hospitals in Delhi and Mumbai accept payment by international credit card and can provide cost estimates in US dollars or other currencies. Currency exchange facilities are available at international airports. Bringing a small amount of cash in US dollars or euros provides a useful backup.

English is an official language of India and the working language of the medical profession throughout the country. At JCI and NABH-accredited hospitals catering to international patients, all clinical communication — consultations, discharge summaries, operative notes — is conducted in English as standard. This is one of India's significant practical advantages as a medical tourism destination.

India's the registry-listed private hospitals have twenty-four-hour emergency departments equipped to manage complex medical emergencies. Travel insurance with medical emergency and repatriation coverage is essential, as uninsured emergency care at private hospitals can be expensive. The national emergency number in India is 112, and most major hospitals have dedicated emergency helplines.

The Consumer Protection Act 2019 covers medical negligence, and patients can file complaints with the District, State, or National Consumer Disputes Redressal Commission. This system is more accessible than traditional civil litigation and has a track record of awarding compensation. The National Medical Commission also handles professional misconduct complaints.

Indian hospitals at the international standard routinely prepare comprehensive discharge packages including operative notes, imaging, pathology reports, and post-operative instructions in English. Before discharge, confirm that all documents have been provided and share them with your GP or relevant specialist at home. The international patient department can liaise directly with home-country physicians if needed.

The major medical tourism cities — Delhi, Mumbai, Chennai, and Hyderabad — are navigable and generally safe for international patients when using established transport and accommodation. The hospitals themselves provide comprehensive support including airport pickup, accommodation assistance, and security within the hospital campus. Standard urban precautions apply in the wider city.

Delhi experiences extreme heat in summer (April to June, exceeding 40°C) and a cool winter (November to February). Mumbai is hot and humid year-round with a heavy monsoon season from June to September. For elective procedures requiring outdoor activity during recovery, the October to March window in northern India is generally the most comfortable. Patients recovering in air-conditioned hospital accommodation are less affected by seasonal variation.

NABH — the National Accreditation Board for Hospitals and Healthcare Providers — is India's domestic hospital accreditation body and operates to standards broadly comparable with JCI, though the two are separate schemes. NABH accreditation is widespread across the Indian private hospital sector and provides a meaningful quality signal for domestic and international patients alike.

Yes. The Indian medical visa includes provision for a companion (attendant) visa for one accompanying family member or carer, which allows them to stay for the duration of the patient's treatment. This is a practical and valued feature for patients undergoing complex or lengthy procedures who require support during their stay.

The internal mammary artery graft — the preferred conduit for the most critical bypass — has a ten-year patency rate exceeding ninety per cent and frequently remains open for twenty years or more. Vein grafts have lower patency rates, with approximately fifty per cent remaining open at ten years. Adherence to cardiac medications and lifestyle modification significantly affects graft longevity.

A stent (percutaneous coronary intervention) is inserted via a catheter through the blood vessel to open a blockage from within, without open surgery. Bypass surgery creates a new route around the blockage using a harvested blood vessel. Bypass is generally preferred for extensive multi-vessel disease or left main artery blockages where stenting is less durable.

Most patients spend five to eight days in hospital following CABG, including one to two days in the intensive care unit. The exact duration depends on the complexity of surgery, the patient's age and general health, and the absence or presence of post-operative complications such as atrial fibrillation or wound issues.

Yes. Lifelong medications typically include antiplatelet therapy (aspirin), statins, beta-blockers, and often ACE inhibitors. These reduce the risk of graft failure, heart attack, and progression of coronary artery disease. Adherence to medication and risk factor management is a critical determinant of long-term outcomes.

Driving is not permitted for four to six weeks after CABG, as the ability to perform an emergency stop is impaired during sternal healing and the patient may still be taking medications affecting alertness. Patients should also check with their driving licence authority, as notification of major cardiac surgery may be required in some countries.

The mortality risk for elective CABG in a low-risk patient at a high-volume centre is approximately one to two per cent. Risk increases with age, emergency surgery, poor left ventricular function, and associated conditions such as kidney disease or diabetes. Patients should ask their surgeon for a risk estimate based on their individual profile.

Light daily activities are possible within two to four weeks of discharge, though sternal precautions limit upper-body exertion for eight to twelve weeks. Return to sedentary work is typically possible at six to eight weeks, and cardiac rehabilitation — which begins four to eight weeks after discharge — progressively rebuilds exercise capacity.

Bypass surgery treats blocked arteries but does not stop the underlying disease process. Long-term success requires smoking cessation, a heart-healthy diet low in saturated fat, regular moderate exercise, blood pressure and cholesterol management, and strict adherence to prescribed medications. Cardiac rehabilitation programmes provide structured support for these changes.
