Summary
Hypertensive heart disease with diastolic dysfunction can be assessed using Doppler, natriuretic peptides, and cardiac sympathetic nerve activity. These markers help evaluate the severity of left ventricular diastolic dysfunction in affected patients.
Area of Science:
- Cardiology
- Medical Imaging
- Neuropeptides
Background:
- Hypertensive heart disease often involves left ventricular diastolic dysfunction.
- Diastolic dysfunction can lead to heart failure and emergent hypertension.
Observation:
- A patient with hypertensive heart disease presented with emergent hypertension and signs of heart failure.
- Echocardiography revealed concentric hypertrophy and restrictive filling patterns.
- 123I-MIBG imaging showed reduced heart-to-mediastinum ratio and increased washout rate.
- Coronary flow reserve was impaired despite normal coronary arteries.
Findings:
- Treatment normalized blood pressure and improved Doppler patterns.
- Plasma levels of atrial natriuretic peptide and brain natriuretic peptide decreased with clinical improvement.
- Impaired coronary flow reserve and altered cardiac sympathetic nerve activity were noted.
Implications:
- Doppler flow velocity patterns are useful for assessing left ventricular diastolic dysfunction.
- Plasma natriuretic peptide levels and cardiac sympathetic activity aid in evaluating diastolic dysfunction severity.
- Coronary flow reserve is a potential indicator for diastolic dysfunction in hypertensive heart disease.
