A 64-year-old woman with hypertension and diabetes presented with acute shortness of breath and left-sides chest discomfort. Electrocardiopgram (ECG) demonstrated Q waves, coved ST-segment elevations, and T-wave inversions in leads V₁-V₄, suggesting acute anterior ST-elevation myocardial infarction (STEMI). catheterization revealed nonocclusive coronary artery disease with elevated pulmonary an...

Background Aortic stiffness is associated with early pulse wave reflection resulting in an increase of cardiac afterload and impairment of coronary perfusion. Experimental data show that high left ventricular pressure due to increased aortic stiffness is associated with enhanced myocardial cell death. We investigated whether aortic stiffness is related to high-sensitivity cardiac troponin T (hs...

Coronary angiography is an invasive procedure that utilises X-ray imaging and contrast medium to visualise the coronary vasculature guide management. Current National Institute for Health Care Excellence guidance aims provide within 72-hours patients with high-risk (GRACE>3%) non-ST elevation myocardial infarction (NSTEMI) late-presenting (>12 hours) ST-elevation (STEMI).

The aim of this study was to describe differences in the characteristics and short- and long-term prognoses of patients with first acute myocardial infarction (MI) according to the presence of ST-segment elevation or non-ST-segment elevation. From 2001 and 2003, 2,048 patients with first MI were consecutively admitted to 6 participating Spanish hospitals and categorized as having ST-segment ele...

Introduction: Primary percutaneous coronary intervention (PPCI) is used for the treatment of ST segment elevation myocardial infarction (STEMI). Anterior STEMI is associated with adverse outcomes, and it is possible that the presence of ramus intermedius (RI) would inversely affect the outcome. This research involved the evaluation of the influence of RI presence on clinical ou...

An issue, which is not addressed by the guidelines, is whether, in the absence of Sgarbossa’s criteria, the association of acute coronary syndrome (ACS) type chest pain and left bundle branch block (LBBB) falls within the province of non-ST segment elevation ACS (nSTE-ACS) or whether it falls within the province of acute myocardial infarction. Strictly speaking, it is only when Sgarbossa’s crit...

Compared to occlusions of other major coronary arteries, patients presenting with acute left circumflex (LCx) occlusion usually have ST-segment elevation on the electrocardiogram <50% of the time, potentially delaying treatment and resulting in worse outcomes. In contemporary practice, little is known about the clinical outcomes of patients with LCx territory occlusion without ST-segment elevat...
