[The importance of mitral calcification in the elderly]
Insights
Mitral calcification (MC) affects 7.7% of elderly individuals, particularly women. This condition is linked to hypertension, aortic stenosis, and heart rhythm disturbances, necessitating careful patient monitoring.
Area of Science:
- Cardiology
- Geriatrics
- Echocardiography
Context:
- Elderly population (over 60 years) echocardiographic study.
- Prevalence of mitral calcification (MC) in this demographic.
- Association of MC with other cardiovascular conditions.
Purpose:
- To investigate the prevalence and characteristics of mitral calcification (MC) in elderly patients.
- To identify associated clinical, metabolic, and cardiac pathologies.
- To understand the implications of MC on cardiac function and rhythm.
Summary:
- Mitral calcification (MC) was found in 7.7% of 480 elderly patients (mean age 75.4), with higher prevalence and severity in women.
- Commonly associated conditions included hypertension (64.9%) and aortic stenosis (10.8%).
- Significant findings also included mitral stenosis/insufficiency (27.0%) and conduction abnormalities (bradyarrhythmias, tachyarrhythmias, intraventricular block).
Impact:
- Highlights the significant prevalence of mitral calcification (MC) in the elderly population.
- Underscores the association of MC with serious cardiovascular issues like hypertension and aortic stenosis.
- Recommends diligent follow-up for early detection and management of MC complications.
Abstract:
The echocardiographic study of 480 patients over 60 years (medium age: 75.4) revealed 37 (33 women) of them having mitral calcification (MC). The analysis of clinical and metabolic data of these 37 patients plus their electro, phono and echocardiographic assessment revealed: 1) MC was observed in 7.7% of this elderly population and its incidence tended to increase with age; 2) MC was more frequent and more pronounced in women; 3) cardiocirculatory abnormalities responsible for a high systolic pressure in the left ventricle, such as hypertension (64.9%) and aortic stenosis (10.8%) were the most commonly associated cardiac pathologies; 4) no history of illnesses usually aggressive to the mitral valve was detected; 5) plasma lipids and calcium were normal; 6) in 27.0% of patients with MC there was some degree of mitral stenosis and/or insufficiency and surgical correction has been considered in some cases; 7) changes in production and/or conduction properties were frequent, causing bradyarrhythmias, tachyarrhythmias and intraventricular block. Taking these points into consideration, a careful follow-up of confirmed cases is suggested, in order to detect and treat any complications without delay.
