Myocardial hypertrophy is a condition in which the muscle cells of the heart (myocardium) increase in size, leading to an enlargement of the heart muscle. This can be a normal response to increased workload on the heart, such as during exercise or pregnancy. However, it can also be a sign of an underlying heart condition, such as high blood pressure, heart valve disease, or cardiomyopathy.
In some cases, myocardial hypertrophy can lead to impaired heart function and an increased risk of heart failure, arrhythmias, and other complications. Treatment for myocardial hypertrophy may include medications to reduce the workload on the heart, lifestyle changes, and in some cases, surgery or other procedures to correct the underlying cause.
It is important for individuals with myocardial hypertrophy to work closely with their healthcare provider to monitor their condition and manage any potential complications.

Myocardial Hypertrophy
Definition:
Myocardial hypertrophy refers to an enlargement of the heart muscle (myocardium) due to an increase in the size of individual cardiomyocytes (heart cells).
Causes:
- Increased workload: Hypertension, aortic stenosis, valvular regurgitation, cardiomyopathy
- Hormonal influences: Growth hormone, thyroid hormone
- Genetic factors: Mutations in genes encoding sarcomere proteins
- Other: Obesity, diabetes, sleep apnea
Types:
- Concentric hypertrophy: Increase in muscle mass with a decrease in ventricular cavity size.
- Eccentric hypertrophy: Increase in ventricular cavity size with a decrease in muscle mass.
- Mixed hypertrophy: A combination of concentric and eccentric hypertrophy.
Consequences:
- Increased myocardial oxygen demand and decreased coronary blood flow
- Impaired diastolic function (relaxation and filling of the heart)
- Increased risk of arrhythmias
- Decreased contractile function (pumping ability of the heart)
- Heart failure
Clinical Features:
- Enlarged heart on physical exam or imaging
- Symptoms of heart failure (e.g., shortness of breath, chest pain, fatigue)
- Abnormal electrocardiogram (ECG)
- Elevated cardiac biomarkers (e.g., troponin, NT-proBNP)
Treatment:
- Treat the underlying cause (e.g., hypertension, aortic stenosis)
- Medications to improve cardiac function and reduce workload (e.g., ACE inhibitors, beta-blockers)
- Device therapy (e.g., pacemakers, defibrillators)
- Surgery (e.g., valve replacement, septal myectomy)
Prognosis:
- Prognosis depends on the underlying cause and severity of hypertrophy.
- Patients with prolonged hypertrophy and impaired cardiac function have a worse prognosis.
