Ischemic Cardiomyopathy develops when the heart muscle is repeatedly or severely deprived of oxygen-rich blood, most commonly because of narrowed or blocked coronary arteries. Previous heart attacks may also damage and scar areas of the heart muscle. Over time, this damage can weaken the left ventricle and reduce its ability to pump blood effectively.
The severity varies between individuals. Some patients may have reduced heart function with few symptoms, while others can develop heart failure, abnormal heart rhythms, or other cardiovascular complications.
Timely evaluation can help determine the extent of coronary artery disease, assess heart function, identify damaged or viable heart muscle, and guide appropriate treatment. Management may help relieve symptoms, reduce the risk of heart failure and dangerous arrhythmias, and improve long-term cardiovascular outcomes in selected patients. Early assessment is particularly important when symptoms such as worsening breathlessness, chest discomfort, fainting, rapid weight gain, or swelling develop.
Causes
Risk Factors
Recent advances in ischemic cardiomyopathy management include improved cardiac MRI to assess heart muscle damage and viability, alongside intravascular imaging techniques such as IVUS to guide coronary interventions. In Malaysia, a 2026 analysis of the National Cardiovascular Database examined IVUS use in more than 40,000 coronary lesions, highlighting its role in selected complex procedures, although availability and cost remain challenges. Treatment increasingly combines personalised heart-failure medication, coronary revascularisation when appropriate, and devices such as implantable cardioverter-defibrillators (ICDs) or cardiac resynchronisation therapy (CRT) for eligible patients. Cardiac rehabilitation and regular follow-up also help support recovery and long-term heart health.
Implantable Cardioverter-Defibrillator (ICD) : Ischemic cardiomyopathy leaves behind myocardial scar tissue, placing patients at high risk for sudden cardiac death via ventricular fibrillation; recommended for selected patients
Cost Start From 16000Explore Options
Cardiac Resynchronisation Therapy (CRT) : For patients with a low ejection fraction and a wide QRS complex (such as a left bundle branch block), a biventricular pacemaker (CRT) restores synchronous ventricular beating.
Left ventricular assist device (LVAD) : A mechanical pump surgically placed in the chest to help the main pumping chamber of the heart circulate blood to the body.
Heart Transplant : The gold-standard replacement of a failing heart with a healthy donor heart.
