Active clinical trials for "Ischemia"

Study of heterogeneity in associations between heart rate and the initial presentation of 12 cardiovascular diseases.

A total of 621 consecutive male and female subjects, without established CAD, referred to exercise stress testing (EST) due to 1) chest pain syndromes or equivocal/equivalent angina with intermediate pretest probability for CAD; 2) , or asymptomatic subjects with diabetes mellitus who are referred EST for risk assessment prior to initiation of an exercise program. To validate the diagnostic performance of the HeartTrends device for the detection and ruling out of myocardial ischemia in a population of subjects who are currently referred for cardiovascular evaluation using EST. Prospective multicenter single-armed study, assessing the diagnostic accuracy of HRV analysis by the HeartTrends device for the detection of myocardial ischemia, as determined by stress echocardiography.

The main objective is to investigate mechanical alternans and MTWA in patients with heart failure caused by coronary artery disease to demonstrate a possible correlation between these two phenomena.

Measurement of reactive oxygen species production and antioxidant system status before and directly after reperfusion of the transplanted kidney and influence of oxidant stress on kidney function in 2 and 6 weeks.
