Right Ventricular Hypertrophy and Pulmonary Hypertension: A Correlation Analysis

Right Ventricular Hypertrophy and Pulmonary Hypertension: A Correlation Analysis Between Tc-99m Tetrofosmin SPECT Adn Echocardiography

The study hypothesis is that a quantitative index can be derived from Tc-99m myocardial perfusion scans that accurately identifies the presence of left ventricular hypertrophy and pulmonary hypertension. Echocardiography provides the reference standard.

Inclusion Criteria:

• Must have an interpretable Tc-99m myocardial perfusion scan and an interpretable echocardiogram.

Exclusion Criteria:

• Technically inadequate noninvasive test.
