This study is a retrospective analysis where coronary arteriograms are being analyzed to determine whether the presence of tortuous coronary arteries correlate with any specific measures of left ventricular mass or left ventricular function on echocardiography.

Inclusion Criteria:

• subjects referred for angiography
• echocardiography performed within 3 months.

Exclusion Criteria:

• connective tissue disease
• severe LV dysfunction
• prior coronary artery bypass surgery
• major adverse coronary event between angiogram and echo procedures
• moderate or greater valve disease
• acute coronary syndrome

Retrospective study of subjects who have undergone clinically-indicated coronary arteriography who also have an echocardiogram that was performed within 3 months of the angiogram.
