A 75-year-old male with long-standing hypertension and angina due to coronary heart disease presents with ankle edema, nocturia, increased shortness of breath with activity, and a chronic nonproductive cough. He has a past history of smoking two packs per day and is an ex-alcoholic. His blood pressure is 170/80 and his heart rate is 100. Electrocardiography and chest radiography indicate the presence of left ventricular hypertrophy.

A. Relate the presence of uncontrolled hypertension and coronary artery disease to the development of heart failure in this man.

B. Explain the significance of left ventricular hypertrophy in terms of both a compensatory mechanism and as a pathologic mechanism in the progression of heart failure.

C. Explain the management and treatment for this diagnosis.

Left ventricular hypertrophy increases the chance of sudden death. Studies have shown that the problem increases the risk of developing some diseases, such as heart failure, stroke, coronary heart disease and even sudden death.

A. How does hypertension cause heart failure?

In summary, heart failure can occur in the natural history of patients with hypertension, as a result of the action of a wide set of adaptive mechanisms triggered by the persistent increase in ventricular afterload, resulting in diastolic or systolic dysfunction.

B. What is the significance of left ventricular hypertrophy in terms of a compensatory mechanism and a pathological mechanism in the progression of heart failure?

The term cardiac hypertrophy refers to increased myocardial mass. It is an adaptive response to a physiological or pathological overload. This adaptation occurs as a response of the heart to an overload of work and can be classified as concentric or eccentric.

C. Explain the management and treatment for this diagnosis.

Treatment depends on the underlying cause and may involve medication or surgery. Left ventricular hypertrophy caused by aortic valve stenosis may require surgery to repair the narrowed valve or to replace it with an artificial valve.

With this information, we can conclude that left ventricular hypertrophy increases the chance of sudden death. Studies have shown that the problem increases the risk of developing some diseases, such as heart failure, stroke, coronary heart disease and even sudden death.
