[Clinical evaluation of nitrates in exercise-induced angina]

Nitroglycerine (NTG) is still the most important angina relief drug. The aim of the study was to evaluate clinical effects and tolerance of sublingually nitroglycerine sub form Nitromint-spray in patients with exercise induced angina pectoris (AP) using treadmill electrocardiography stress test (EST). The study group consisted of 40 adults patients (mean age 57.4 +/- 10.08 years) hospitalised in our clinic with AP confirmed by clinically and electrocardiographically positive EST. Tests were performed using treadmill Marquette-Centra equipment, according to the modified Bruce protocol after 3 days wash-out period. On the fourth day two ESTs were performed: EST-0 and 30 minutes later EST-NTG after sublingual administration 0.8 mg of NTG. Among measured parameters after NTG exercise induced ST segment depression decline from 2.3 +/- 1.0 to 1.5 +/- 0.8 (p < 0.0001). EST after NTG became electrocardiographically negative in 11 patients. NTG increased workload, and time to angina pain oneset (p < 0.0001). Nitromint-spray proved to be clinically effective, well tolerated and easy to use.
