Gender-based differences in cardiac diseases.

Area of Science:

• Cardiology
• Genetics
• Molecular Biology

Background:

• Cardiovascular diseases exhibit distinct sex-based prevalence and presentation patterns.
• Heart failure and Brugada syndrome are more common in men.
• Women are more susceptible to QT interval prolongation and torsades de pointes (TdP).

Purpose of the Study:

• To review current knowledge on gender differences in cardiac repolarization.
• To explore molecular mechanisms underlying sex-based variations in heart conditions.
• To correlate these differences with clinical manifestations of heart failure, Brugada syndrome, and long QT syndrome.

Main Methods:

• Literature review of recent studies on cardiac repolarization and gender differences.
• Analysis of molecular mechanisms and genetic factors.
• Synthesis of clinical data on heart failure, Brugada syndrome, and long QT syndrome presentation by gender.

Main Results:

• Significant gender disparities exist in the incidence and clinical presentation of major cardiac syndromes.
• Advances in understanding abnormal repolarization have highlighted the role of sex-specific factors.
• Despite progress, the precise etiological basis for these gender-based differences is not fully elucidated.

Conclusions:

• Gender significantly influences cardiac repolarization and the susceptibility to specific cardiovascular diseases.
• Further research into molecular and genetic underpinnings is crucial for understanding sex differences in heart disease.
• Tailoring clinical approaches based on gender may improve patient outcomes for conditions like heart failure, Brugada syndrome, and long QT syndrome.
