However, predictors of LVA formation in early period are inadequately defined.ObjectivesThe purpose of this study is to determine potential predictors of LVA formation in early period (

Authors: Kurisu S, Nitta K, Sumimoto Y, Ikenaga H, Ishibashi K, Fukuda Y, Kihara Y Abstract Objective The frontal QRS-T angle on a 12-lead electrocardiogram (ECG) has recently become accepted as a variable of ventricular repolarization. We compared the effects of myocardial perfusion defect (MPD) on the frontal QRS-T angle between anterior and inferior myocardial infarction (MI) using single-photon emission computed tomography. Methods The frontal QRS-T angle was defined as the absolute value of the difference between the frontal plane QRS axis and T-wave axis. A QRS-T angle more than 90° was considered abnorma...

Abstract The TWIK-related K+ channel (TREK-1) is a two-pore-domain potassium channel that produces background leaky potassium currents. TREK-1 has a protective role against ischemia-induced neuronal damage. TREK-1 is also expressed in the heart, but its role in myocardial ischemia-reperfusion (IR)-induced injury has not been examined. In the current study, we used a TREK-1 knockout (KO) mouse model to show that TREK-1 has a critical role in the cardiac I/R-induced injury and during remodeling after myocardial infarction (MI). At baseline, TREK-1 KO mice had similar blood pressure and heart rate as the wild-type (W...

DiscussionRemote monitoring may improve clinical outcome if it uncovers conditions with low symptom burden which cause or indicate an increased risk. A simple and easily implementable response to the information is important. Cardiac arrhythmias frequently start as asymptomatic, shorter lasting, and nightly events. The BIO-GUARD-MI trial represents the first attempt to simplify the response to the rather complex nature of heart arrhythmias.Trial registrationClinical Trials,NCT02341534.

We examined the incidence of high-sensitivity cardiac troponin I (hs-cTNI) level elevation, electrocardiogram (ECG) findings, and data on clinical management.ResultsAmong the TGA patients, 17 (8.4%) exhibited elevated levels of hs-cTNI. Although none of the patients had ST elevation, 12 (6.7%) showed QTc prolongation and 11 (6.1%) an inverted T wave on ECG. No typical clinical symptoms suggestive of myocardial infarction were present in any of the cases, however, 17 (8.4%) patients complained of mild somatic symptoms. Patients with hs-cTNI level elevation had a significantly greater likelihood of a history of coronary hear...

We present a case where myocardial ischemia on non-ECG-gated CECT corroborated clinical and electrocardiographic information allowing for the early diagnosis and treatment of an atypical presentation of acute coronary syndrome (ACS) prior to troponin elevation.

Abstract Objectives: Incomplete ST-segment elevation resolution (STR) occasionally occurs despite successful revascularization of epicardial coronary artery after primary percutaneous coronary intervention (PPCI). The aim of this study was to evaluate the relationship between the degree of STR and the severity of microvascular dysfunction. Methods: A total of 73 consecutive patients with ST-segment elevation myocardial infarction (STEMI) who underwent successful PPCI were evaluated. Serial 12-lead electrocardiography was performed at baseline and at 90 minutes after PPCI. Microvascular dysfunction was ...

AbstractPurpose of ReviewThe long-term use of opioid and cannabinoid medications to control chronic pain and treat opioid use disorders now involves a large proportion of the population in the United States. Yet, the cardiovascular risks of opioids are not well understood. This systematic review summarizes the current literature to assess the potential cardiovascular disease risks associated with opioid and cannabinoid medications.Recent FindingsThe role of long-term methadone use in increasing QT interval among people receiving methadone treatment for substance use disorders is well established. Routine electrocardiogram ...

lez J Abstract A new or presumably new left bundle branch block along with ischemic symptoms has traditionally been considered an electrocardiographic equivalent of ST-segment elevation myocardial infarction, which should be brought to emergent reperfusion. However, several criteria have been proposed for its definition, but none has reached out an optimal diagnostic yield. Below we detail these criteria, their main problems and the advantages they have shown. PMID: 31448761 [PubMed - in process]
