OBJECTIVES We sought to determine the electrocardiographic (ECG) features associated with acute left main coronary artery (LMCA) obstruction. BACKGROUND Prediction of LMCA obstruction is important with regard to selecting the appropriate treatment strategy, because acute LMCA obstruction usually causes severe hemodynamic deterioration, resulting in a less favorable prognosis. METHODS We stu...

results prediction of the rca as culprit lesion using tierala's algorithm was 86% sensitive and 50% specific. prediction of lcx occlusion based on st-elevation ≥ 1 mm in v6 was 87% specific (p = 0.005). sum of st elevation in leads v5 and v6 more than 2.5 mm, was a good marker of lcx prediction (p = 0.044). st-elevation in v4r was 48% sensitive and 89% specific for rca prediction (p = 0.004). w...

BACKGROUND The aim was to ascertain the 1-year clinical outcomes of 1,234 patients who underwent implantations of sirolimus-eluting stents (SES) for acute myocardial infarction (MI) in the multinational e-SELECT registry. METHODS Fifteen thousand and one hundred and forty-seven patients treated with SES were entered in the e-SELECT registry, of whom 1,234 presented within <24 hours of onset o...

BACKGROUND Outcomes in patients with mild to moderate renal function (RF) abnormalities presenting with acute coronary syndromes (ACS) are not well defined. METHODS AND RESULTS A convenience sample of 4 ACS trial databases including all enrolled patients was assessed to determine 30- and 180-day outcomes. The 4 trials were Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) II...

ST-elevation ACS (STE-ACS): patients present with acute chest pain and persistent (>20 minutes) ST-segment elevation. Most of these patients will develop an ST-elevation myocardial infarction (STEMI). Non-ST-elevation ACS (NSTE-ACS): patients present with acute chest pain but without persistent STsegment elevation. The ECG shows persistent or transient ST-segment depression or T-wave inversion,...

Objective: To determine the spectrum of arrhythmias during initial 48 hours AMI and their impact on in-hospital outcome.&#x0D; Study Design: Analytical Cross-sectional study.&#x0D; Place Duration Study: This study was conducted at a Tertiary Cardiac Center Rawalpindi Pakistan from Jun 2021 till Jan 2022.&#x0D; Methodology: A total (n=150) patients Acute Myocardial Infarction (AMI) undergoing im...

Patients The development set comprised data from 13 253 patients who had ST elevation MI and were enrolled within 6 hours of symptom onset, and who did not have a history of cerebrovascular disease, systolic blood pressure (SBP) > 180 mm Hg, diastolic blood pressure (DBP) > 110 mm Hg, cardiogenic shock, or increased risk of severe bleeding. The validation set comprised data from 3659 patients w...

To the Editor: Transient left ventricular apical ballooning (AB) is characterized as a reversible apical balloon-like left ventricular wall motion abnormality. In contrast to patients with acute myocardial infarction (MI), patients with AB do not have obstructive coronary heart disease (CHD) and experience almost complete recovery of cardiac function. Excess sympathetic activity and cardiac sym...

Patient history, physical examination, 12-lead electrocardiogram (ECG) and cardiac biomarkers are key components of an effective chest pain assessment. The first priority is excluding serious chest pain syndromes, namely acute coronary syndromes (ACSs), aortic dissection, pulmonary embolism, cardiac tamponade and tension pneumothorax. On history, the mnemonic SOCRATES (Site Onset Character Radi...
