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...

To determine the presence of anticardiolipin (aCL) antibodies in patients with ischemic events, we designed a case-control study. We studied 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 control subjects with no evidence of ischemic heart disease. Plasma samples were assessed for IgG anticardiolipin antibodies by enzyme-linked immunosorbent assay (ELI...

Objective: To find outthe frequency of cardiogenic shock in patients with ACS Study design: Cross sectional study Methodology:A calculated sample 240 presented acute coronary syndrome confirmed clinically and/or on the basis ECG and cardiac markers was taken. In addition to collecting basic demographic details were inquired about presence risk factors (smoking status, diabetesand hypertension)....

BACKGROUND Antibody antioxidized low density lipoproteins (oxLDL) might play a role both in atherogenesis and in the pathogenesis of acute coronary syndromes. METHODS AND RESULTS Antibody titres to oxLDL and levels of C-reactive protein were compared in unstable angina, stable angina or peripheral artery disease. Antibody titres to LDL oxidated by CuSO(4)for 2, 4 and 18 h (Cu-oxLDL-Ab(2-4-18)...

BACKGROUND Although the role of enteroviruses has been proved in heart diseases, extensive information is not available on the association between enteroviruses and unstable angina. In the present study, the authors compared the prevalence of enteroviruses in patients with and without unstable angina. METHODS Blood samples were taken from 51 patients with unstable angina and 55 patients witho...
