Non-invasive evaluation for pulmonary circulatory impairment during exercise in patients with chronic lung disease; With thallium-201 myocardial scintigraphy

Journal Article:

Abstract

Thallium-201 myocardial scintigraphy was performed at rest and during exercise on sixteen patients with chronic lung disease to evaluate the secondary pulmonary hypertension during exercise with non-invasive technique. An inverse significant correlation was found between thallium activity ratio (TAR) of left ventricle plus ventricular septum to right ventricle and both of pulmonary vascular resistance and right to left ventricular work index ratio during exercise. The patients were divided into three groups according to mean pulmonary arterial pressure (P-bar{sub PA}) at rest and during exercise: the first group consisted of six patients with pulmonary hypertension during exercise (P-bar{sub PA}: below 25 mmHg at rest and above 30 mmHg during exercise), the second group consisted of four patients with pulmonary hypertension at rest (P-bar{sub PA} above 25 mmHg at rest), and the third group consisted of six patients without pulmonary hypertension (P-bar{sub PA} below 25 mmHg at rest, below 30 mmHg during exercise). In the first group, TAR during exercise was lowered than at rest in four patients, and in the second group TAR during exercise was lowered than at rest in all, while in the third group TAR during exercise was increased than at rest in five patients.
