Effects of Myocardial Perfusion Defect on the Frontal QRS-T Angle in Anterior Versus Inferior Myocardial Infarction.

Effects of Myocardial Perfusion Defect on the Frontal QRS-T Angle in Anterior Versus Inferior Myocardial Infarction. Intern Med. 2019 Sep 11;: 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 abnormal. Patients Forty-two patients with anterior MI and 42 age- and sex-matched patients with inferior MI were enrolled. For controls, 42 age- and sex-matched patients with no MPD were selected. Results The mean frontal QRS-T angles in anterior MI, inferior MI and control subjects were 94.7±46.2°, 26.7±22.1° and 27.0±23.2°, respectively. Compared with controls, the frontal QRS-T angle was larger in anterior MI subjects (p

Vascular inflammation was suggested as an important contributor to atherosclerosis half a century ago [1]. Lately, and finally, in the CANTOS Trial [2], the application of 150 mg canakinumab, a monoclonal antibody targeting interleukin-1 β, resulted in a 15% relative risk reduction, independent of lipid lowering. Thus, the last remaining doubters of the inflammation hypothesis in general were silenced. In addition, plaques in the artery wall were demonstrated to rupture more likely when inflammation is present; and plaque rupture i s a common cause for myocardial infarction and cardiovascular death [2,3].

Background The primary cause of death among African American women older than 50 years is cardiovascular disease. Cardiovascular disease affects more than 16.8 million Americans and occurs when plaque builds up in the arteries that provide blood to the heart. This often leads to a partial or complete blockage, causing a myocardial infarction (heart attack). There is limited research regarding the lived experiences of African American women before and after a myocardial infarction. Objective The purpose of this qualitative study was to explore the experiences of African American women living in the southern region of t...

Authors: Alexopoulos D, Sfantou D, Lianos I, Pappas C, Revela I, Triantafyllidi H, Ikonomidis I Abstract Given that patients with prior myocardial infarction and features of high ischemic and low bleeding risk may benefit by extending dual antiplatelet therapy beyond 1 year, we aimed of assessing platelet reactivity provided by ticagrelor 60 mg bid versus prasugrel 5 mg od in 20 such patients participating in a randomized, crossover study. The primary end point of platelet reactivity at the end of the two treatment periods (by VerifyNow, in PRU) was significantly lower for ticagrelor (31.9 PRU [95% CI 12.3-51.4]) c...

We’re so good at sleeping we can even do it with our eyes shut. Still, there’s always room for improvement. Sleep tracking is a great way to get to know ourselves a bit better and even improve our way of life. It’s expensive and complicated to get a professional sleep analysis but with health gadgets on the rise, we have more and more options to take things in our own hands. SleepOn Go2Sleep promises to help us understand our sleeping patterns better through its ring-shaped sleep tracker. We got curious what it can do, so we tested it for a couple of days. Here’s our comprehensive review. Big ide...

T cell autoreactivity is a hallmark of autoimmune diseases but can also benefit self-maintenance and foster tissue repair. Here, we investigated whether heart-specific T cells exert salutary or detrimental effects in the context of myocardial infarction (MI), the leading cause of death worldwide. After screening more than 150 class II–restricted epitopes, we found that myosin heavy chain α (MYHCA) was a dominant cardiac antigen triggering post-MI CD4+ T cell activation in Balb/c mice. Transferred MYHCA614–629-specific CD4+ T cells (TCR-M cells) selectively accumulated in the myocardium and mediastinal lym...

Cardiac tissue necrosis secondary to coronary artery occlusion is one of the most common and deadly sterile injuries in developed countries. In this issue of the JCI, Rieckmann et al. identified and characterized antigen-specific CD4+ T helper (Th) cells that developed in the context of myocardial infarction (MI) in mice. They showed that myosin heavy chain α (MYHCA) is a dominant cardiac autoantigen and that T cells with T cell receptor (TCR) specificity to MYHCA acquired a Treg phenotype when adoptively transferred into infarcted mice, which mediated a cardioprotective healing response. Thus, Rieckmann et al. showe...
