New protocol to detect coronary spastic angina without fixed stenosis.
A new combined test, accelerated exercise following mild hyperventilation (HV), was examined to determine whether it is effective at detecting a positive response in patients with pharmacologically-induced coronary vasospasm and near normal coronary arteries. Fifty-eight consecutive patients who underwent both triple non-invasive spasm provocation tests and diagnostic coronary angiography were ...
متن کاملLimited role of coronary angioplasty and stenting in coronary spastic angina with organic stenosis.
OBJECTIVES We investigated the efficacy of percutaneous coronary intervention (PCI) in patients with coronary spastic angina (CSA) and severe organic stenosis. BACKGROUND Coronary spasm occurs at the site of organic stenosis in most patients with CSA and severe stenosis, whereas multivessel spasm occurs frequently in those with normal coronary arteries. The incidence of multivessel spasm and ...
متن کاملTreatment of Coronary Spastic Angina, Particularly Medically Refractory Coronary Spasm
Coronary spasm plays an important role in the pathogenesis of variant angina as well as ischaemic heart diseases. Treatment with vasodilators such as long-acting calcium channel blockers and long-acting nitrates is generally effective in preventing coronary spasm; however, in some patients coronary spasm is refractory to standard therapy. Because of endothelial dysfunction, hyper-reactivity of ...
متن کاملIntermediate fixed coronary artery stenosis at the site of ergonovine-provoked spasm as a predictor of long-term major adverse cardiac events of patients with coronary spastic angina.
BACKGROUND Organic coronary artery stenosis is a significant prognostic factor in patients with coronary spastic angina (CSA), so the present study was focused on assessing the impact of intermediate fixed stenosis at sites of provoked spasm on the long-term outcomes of CSA patients. METHODS AND RESULTS CSA patients diagnosed on the basis of ergonovine-provoked spasm were enrolled and the cli...
متن کاملCoronary embolism and angina in mitral stenosis.
Coronary embolism has been considered a rare and often fatal mishap. The most frequently reported heart diseases causing coronary embolism have been syphilis and bacterial endocarditis (Shrader et al., 1956), so that coronary embolism might be expected to be decreasing in frequency. Our experience suggests, however, that its occurrence is by no means rare in rheumatic heart disease. The object ...
