Study Comparing Single-Visit Package vs Standard Investigations for Diagnosing Chronic Coronary Artery Disease in Swedish Primary Care

What this Trial Is About

Researchers are evaluating a new combined procedure to investigate possible coronary heart disease, comparing it to the standard stepwise approach. The study aims to determine if this package investigation, which includes a myocardial perfusion scan, echocardiography, and heart CT scan all done in a single visit, is faster, less costly, or more costly. The trial also looks at how these approaches affect patients physical activity, mental well-being, adherence to heart-protective medications, and risk of cardiac events like heart attacks over several years. The study compares two groups one receiving the package investigation during one hospital visit, and the other undergoing the standard investigation involving sequential tests such as exercise stress bicycle test, echocardiography, and myocardial perfusion scan as needed. Both groups receive resting ECG and risk evaluation before further testing. Additional data from a heart sound recording device Cadscore4 is collected for scientific analysis but not used clinically. Participants are patients from primary care centers with chest symptoms and an intermediate risk for coronary artery disease. They give consent to answer questionnaires at enrollment and at one, three, and five years, and allow researchers access to medical records and registry data. The study measures include time to complete ischemia assessment, costs, health quality, physical fitness, anxiety, depression, medication adherence, and heart events, with follow-up lasting up to five years.
