A reversible cause of left ventricular dysfunction: Case report and brief review

Area of Science:

• Cardiology
• Endocrinology
• Internal Medicine

Background:

• Diabetic ketoacidosis (DKA) is a serious complication of diabetes.
• Cardiovascular manifestations of DKA are not always apparent.
• Metabolic disorders can affect cardiac function.

Observation:

• A patient presented with DKA and elevated cardiac biomarkers (troponin I, natriuretic peptides).
• ECG showed repolarization abnormalities.
• Transthoracic echocardiogram revealed severe left ventricular systolic dysfunction.

Findings:

• DKA was identified as the likely cause of the cardiac dysfunction.
• Left ventricular function normalized within seven days.
• Profile L heart failure was diagnosed concurrently.

Implications:

• Metabolic and electrolyte disturbances, particularly DKA, should be considered in the differential diagnosis of new-onset heart failure.
• This case highlights a potential cardiovascular impact of diabetes.
• Early recognition of DKA-induced cardiomyopathy is essential for timely intervention.
