BACKGROUND Early awareness, recognition, and treatment of angina can help prevent or delay an acute myocardial infarction and potentially delay death. A patient's educational level may affect a physician's diagnosis of angina and/or a patient's symptom recognition. The objective of this study was to determine whether low education is a risk factor for undiagnosed angina. METHODS This was a cr...

background: the complicated concept of quality of life (qol) has been considered as an important criterion for health outcomes in chronic diseases, such as heart disease, in recent years. the aim of this study was to evaluate the qol of patients with angina pectoris after treatment with enhanced external counterpulsation (eecp). methods and materials: this quasi-experimental study was conducted...

INTRODUCTION Unstable angina is associated with an acute systemic inflammatory reaction and circulating T lymphocytes are activated. We investigated whether in unstable angina with marked immune system activation a selective upregulation of the circulating T-cell renin-angiotensin system, modulated by angiotensin II, could occur. METHODS We studied 13 unstable angina patients, 10 patients wit...

One hundred and five patients with unstable angina and 175 with chronic stable angina were treated by primary percutaneous transluminal coronary angioplasty. Patients with unstable angina had had symptoms for a shorter time and were more likely to have angiographically complex lesions and lesions less than 10 mm in length than patients with chronic stable angina. Other baseline variables were n...

To define more completely regional coronary hemodynamic changes that occur during spontaneous angina pectoris in patients with variant angina, we measured coronary sinus and great cardiac vein blood flow (CSF and GCVF) and aortic and left ventricular pressures before and during spontaneous angina in six patients with variant angina. During spontaneous angina, ECGs in four patients showed eviden...

BACKGROUND Pre-infarction angina reduces myocardial infarct size by preventing the myocardium from being subjected to ischemia reperfusion (I/R) injury. Ischemic preconditioning is the proposed mechanism for this effect. Sphingosine 1 phosphate (S1P) activates ischemic preconditioning pathways and may play a role in the presence of cardioprotective effects of pre-infarction angina. Therefore, w...

BACKGROUND As new techniques emerge to quantify patients' health status, new opportunities are created to validate patient-reported outcome questionnaires. The Seattle Angina Questionnaire (SAQ), a widely used coronary artery disease-specific health status tool, has not been validated against daily records of angina frequency and sublingual nitroglycerin (SL NTG) use. Additional evidence suppor...
