OBJECTIVE: To determine, in patients with ST-segment Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI), the prognostic weight of cardiac arrest (CA) according to the type of rhythm (shockable vs. non-shockable). METHODS: We prospectively enrolled 3278 consecutive STEMI patients undergoing PPCI. Multivariable Cox regression was used to establish the relation to 1-year cardiac mortality of both type of CA. In patients suffering from CA we identified predictors of both poor neurological outcome (cerebral performance categories 3-5) and cardiac mortality at 1year...

BACKGROUND: Transradial access (TRA) is preferred for coronary angiography (CA) or percutaneous coronary intervention due to reduced access-related complications, and mortality especially for patients with ST elevation myocardial infarction. Radial artery occlusion (RAO) is a known complication of TRA, and precludes its use as a future access site, conduit for coronary artery bypass grafting or for hemodialysis fistula placement. Although a standard dose (SD) heparin of 5000 Units is used during TRA, the risks of RAO and hematoma compared to lower dose (LD) remain unclear...

BACKGROUND: Since older age is a strong predictor of not only bleeding but also of ischemic events, understanding the risk:benefit profile of bivalirudin in the elderly undergoing primary percutaneous coronary intervention (pPCI) for ST-segment elevation (STEMI) is important. For this, we aim to compare elderly with young patients, who all underwent pPCI for STEMI and randomly received either bivalirudin or heparin. METHODS: We performed a patient-level pooled analysis (n=5800) of two large randomized trials...

BACKGROUND: Recent randomized evidence has demonstrated benefit with complete revascularization during the index hospitalization for multivessel coronary artery disease ST-segment elevation myocardial infarction (STEMI) patients; however, this benefit likely depends on the risk of future major adverse cardiovascular events (MACE). METHODS: Using data from Duke University Medical Center (2003-2012), we identified those at high risk for 1-year MACE among 664 STEMI patients with conservatively managed non-infarct-related artery (non-IRA) lesions...

BACKGROUND: The clinical benefit of manual thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) in patients with ST-segment elevation myocardial infarction (STEMI) remains uncertain. This study assessed the impact of circadian rhythms on the effectiveness of manual TA. METHODS AND RESULTS: We conducted an observational study of patients enrolled in the Acute Myocardial Infarction in Switzerland Plus registry. STEMI patients undergoing PPCI with (TA group) or without (PCI-alone group) manual TA were divided based on time-of-day symptom onset: group 1 (00:00-05:59), group 2 (06:00-11:59), group 3 (12:00-17:59) and group 4 (18:00-23:59)...

REVIEW
William F Fearon, Yuhei Kobayashi
Traditionally, invasive coronary physiological assessment has focused on the epicardial coronary artery. More recently, appreciation of the importance of the coronary microvasculature in determining patient outcomes has grown. Several invasive modalities for interrogating microvascular function have been proposed. Angiographic techniques have been limited by their qualitative and subjective nature. Doppler wire-derived coronary flow reserve has been applied in research studies, but its clinical role has been limited by its lack of reproducibility, its lack of a clear normal value, and the fact that it is not specific for the microvasculature but interrogates the entire coronary circulation...

Post-infarction ventricular septal defect (VSD) is a rare but potentially lethal complication of acute myocardial infarction. Medical management is usually futile, so definitive surgery remains the treatment of choice but the risk surgery is very high and the optimal timing for surgery is still under debate. A 55-year-old man with no previous medical history attended the emergency-room for 12 h evolution of oppressive chest pain and strong anginal pain 7 days ago. On physical examination, blood pressure was 96/70 mmHg, pansystolic murmur over left sternal border without pulmonary crackles...

Introduction: Atherosclerosis is considered the pathophysiology underlying cardiovascular (CVD), cerebrovascular, and peripheral vascular diseases. Evidence supporting an autoimmune component is emerging, with imaging studies correlating MYC-associated zinc finger protein antibody (MAZ-Ab) optical density (OD) with plaque activity. This study compares MAZ-Ab OD on ELISA testing among patients presenting with acute coronary syndromes (ACSs) to healthy controls and investigates the association of MAZ-Ab to traditional CVD risk factors...

Coronary heart disease (CHD) is the most common cause of heart disease and is the single most important cause of premature death in developed world. Recognizing a patient with ACS is important because the diagnosis triggers both triage and management. cTnI is 100% tissue-specific for the myocardium and it has been shown to be a very sensitive and specific marker for acute myocardial infarction (AMI). Ventricular function is the best predictor of death after an acute coronary syndrome. It serves as a marker of myocardial damage, provides information on systolic function as well as diagnosis and prognosis...

Myrtenol is a monoterpene with multiple pharmacological activities. However, although monoterpenes have been proposed to play beneficial roles in a variety of cardiac disorders, pharmacological actions of myrtenol in the heart are not yet reported. Hence, the aim of this study was to evaluate whether myrtenol promotes cardioprotection against myocardial ischemia-reperfusion (IR) injury, and the mechanisms involved in these effects. Male Wistar rats were orally treated for seven consecutive days with myrtenol (50 mg/kg) or N-acetyl cysteine (1...

BACKGROUND: Drug-eluting stents (DES) represent a significant evolution in the treatment of patients with acute myocardial infarction with ST elevation. However, stent-related adverse events have led to an introduction of drug-coated balloons (DCB) applied particularly to bifurcation lesions, in-stent restenosis and small vessel disease. The aim of this study was to determine whether a DCB-only strategy has a similar safety profile and equal angiographic and clinical outcomes to DES implantation in primary percutaneous coronary intervention (pPCI)...

Introduction: Among the 12 leads studied in electrocardiography (ECG), lead aVR can be considered as the most forgotten part of it since no attention is paid to it as the mirror image of other leads. Therefore, the present study has been designed with the aim of evaluating the prevalence of ST segment changes in lead aVR and its relationship with the outcome of these patients. Methods: In this retrospective cross sectional study medical profiles of patients who had presented to emergency department with the final diagnosis of myocardial infarction (MI) in a 4-year period were evaluated regarding changes of ST segment in lead aVR and its relationship with in-hospital mortality, the number of vessels involved, infarct location and cardiac ejection fraction...

Over the last decade, systems of care for ST-elevation myocardial infarction (STEMI) have evolved to try to improve outcomes and timely access to percutaneous coronary intervention (PCI). There have also been advances in PCI techniques and adjunctive pharmacotherapies. In this study, we sought to determine temporal changes in practices and clinical outcomes of PCI in patients with STEMI. We prospectively collected data on 8,412 consecutive patients undergoing PCI for STEMI between 2005 and 2016 in the multicenter Melbourne Interventional Group registry...
