[Cardiac failure in ischemic cardiopathy]

Area of Science:

• Cardiology
• Internal Medicine
• Pathophysiology

Background:

• Heart failure is a leading cause of illness and death, posing a major public health challenge.
• Myocardial dysfunction underlies heart failure, impairing the heart's ability to meet metabolic demands.
• Ischemic heart disease is the primary cause, often leading to left ventricular systolic dysfunction, but diastolic dysfunction also occurs, especially in the elderly.

Purpose of the Study:

• To highlight the significance of heart failure as a recognized health problem.
• To emphasize the role of myocardial dysfunction in cardiac failure.
• To underscore the importance of echocardiographic screening for identifying undiagnosed cases and improving therapeutic management.

Main Methods:

• Review of the pathophysiology of heart failure.
• Discussion of common causes, particularly ischemic heart disease and myocardial infarction.
• Emphasis on diagnostic approaches like echocardiography for left ventricular dysfunction.

Main Results:

• Ischemic heart disease frequently causes left ventricular systolic dysfunction and heart failure.
• Myocardial infarction can lead to ventricular remodeling, subsequent systolic and diastolic dysfunction, and heart failure.
• A significant number of patients with heart failure or left ventricular dysfunction remain undiagnosed.

Conclusions:

• Myocardial dysfunction is central to heart failure, often initiated by ischemic events.
• Echocardiographic screening is vital for identifying patients with left ventricular dysfunction.
• Improved diagnostic strategies can enhance the therapeutic management of cardiac dysfunction.
