Hpertrophic subaortic stenosis is not rare in the eighth decade

Area of Science:

• Cardiology
• Internal Medicine
• Geriatrics

Background:

• Idiopathic hypertrophic subaortic stenosis (IHSS) is a significant cause of symptomatic heart disease.
• Diagnosis of IHSS is often delayed or missed, particularly in elderly patients.
• Previous studies have focused less on IHSS in older populations.

Purpose of the Study:

• To investigate the prevalence and diagnostic challenges of idiopathic hypertrophic subaortic stenosis in elderly patients.
• To compare the clinical presentation and diagnostic accuracy of IHSS between younger and older patient groups.
• To emphasize the importance of considering IHSS in elderly individuals with unexplained heart murmurs.

Main Methods:

• Retrospective analysis of patients diagnosed with IHSS over a five-year period.
• Comparison of diagnostic accuracy, clinical features, and cardiac catheterization/echocardiographic findings between younger (<67 years) and older (70-79 years) patient groups.
• Review of referral diagnoses, symptoms, physical findings, and electrocardiographic observations.

Main Results:

• IHSS was diagnosed in 9 older patients (70-79 years) and 26 younger patients (20-66 years).
• Only 1 older patient (11%) received the correct initial diagnosis, compared to 19 younger patients (73%).
• Coronary artery disease was more frequent in older patients (60% vs. 23%). Echocardiography confirmed IHSS in 5 older patients and cardiac catheterization in the remaining 4.

Conclusions:

• Idiopathic hypertrophic subaortic stenosis is not rare in the eighth decade of life.
• A high index of suspicion and definitive diagnostic studies like echocardiography are essential for accurate IHSS diagnosis in the elderly.
• Accurate diagnosis is fundamental for appropriate management of IHSS, regardless of patient age.
