The effects of each drug on hemodynamics during exercise-induced angina were determined by exercise testing in the control state and after the maximum cumulative dose of each drug.

      Re: Angina and blood oxygen I'm not sure of what kind of oximeter you have (ear, finger, etc.) However unless it is able to measure the oxygen flow in the very smallest arteries of the heart (impossible, of course) it won't be of any use in diagnosing angina. 2) Peripheral Edema 3) Nifedipine (makes angina worse in %10; avoid short acting nifedipine) 4) Verapamil- Bradycardia, Constipation, monitor for signs of HF, and will increase digoxin plasma concentrations 5) Diltiazem- Similar side effects as verapamil but not as much myocardial depression.

Breathing CO to raise the COHb from % to % caused a decrease in exercise duration until angina pectoris (p less than ) and a reduction in product of systolic blood pressure times heart rate at the onset of angina (p less than ).

These data indicate that a 2% COHb level aggravates angina pectoris due to coronary artery by: Aggravation of angina pectoris by two percent carboxyhemoglobin A double-blind, randomized, crossover study was performed in 15 patients with stable angina to evaluate the effect of breathing carbon monoxide (CO), which raised the carboxyhemoglobin (COHb) from % to %, versus breathing compressed, purified air, which lowered the COHb from Cited by: Breathing CO to raise the COHb from % to % caused a decrease in exercise duration until angina pectoris (p angina (p 2% COHb level aggravates angina pectoris due to coronary artery by:   In a double-blind study, 10 patients with angina exercised until they developed angina, before and after breathing 50 ppm carbon monoxide on two mornings for 2 hours and compressed, purified air on two mornings for 2 hours.

The mean arteriovenous difference was% COHb (95%CI,% to%), with 95% of the differences ranging from % COHb to % COHb. Conclusion: Venous COHb levels predict arterial levels with a high degree of accuracy.

Angina pectoris is a clinical syndrome of precordial discomfort or pressure due to transient myocardial ischemia without infarction. It is typically precipitated by exertion or psychologic stress and relieved by rest or sublingual nitroglycerin.

Diagnosis is by symptoms, ECG, and myocardial imaging. In addition, there were % (p = ) and % (p = ) decreases in time to the onset of angina after exposures producing and % COHb, respectively, compared to the control day.
