Cardiovascular abnormalities in autosomal-dominant polycystic kidney disease

Area of Science:

• Nephrology
• Cardiology
• Genetics

Background:

• Cardiovascular disease is a leading cause of death in autosomal-dominant polycystic kidney disease (ADPKD).
• Hypertension is a frequent early sign, affecting 60% of patients before significant kidney impairment.
• Hypertension accelerates end-stage renal disease and is a key treatable factor in ADPKD.

Purpose of the Study:

• To investigate the early cardiovascular manifestations in ADPKD patients.
• To highlight the role of hypertension and left ventricular hypertrophy in ADPKD cardiovascular complications.
• To assess the potential of early intervention to mitigate ADPKD-related cardiovascular and renal decline.

Main Methods:

• The study reviewed existing literature on cardiovascular complications in ADPKD.
• Analysis focused on the prevalence and impact of hypertension and left ventricular hypertrophy.
• Evaluation of early markers of cardiovascular dysfunction, including diastolic dysfunction and endothelial function.

Main Results:

• Hypertension and left ventricular hypertrophy are prevalent and significant risk factors for cardiovascular morbidity and mortality in ADPKD.
• Subtle cardiovascular changes like diastolic dysfunction and endothelial dysfunction are detectable even in young ADPKD patients with normal blood pressure and renal function.
• These findings indicate that cardiovascular involvement begins early in ADPKD.

Conclusions:

• Cardiovascular complications are a major concern in ADPKD, starting early in the disease course.
• Early detection and management of hypertension, particularly with renin-angiotensin-aldosterone system inhibitors, are crucial.
• Interventions targeting hypertension may reduce cardiovascular risks and slow kidney disease progression in ADPKD.
