Regional Strain Determination and Myocardial Infarction Detection by Three‐Dimensional Echocardiography with Varied Temporal Resolution

This study aims to evaluate the feasibility and accuracy of 3DE on longitudinal and circumferential strain (LS, CS) determination and infarction detection under variable frame rates (FR) and “heart rates” (stroke rates [SR]) conditions. MethodsLatex balloons were sewn into the left ventricle (LV) of 20 freshly harvested pig hearts which were then passively driven by a pulsatile pump apparatus at stroke volumes (SV) 30–70 mL. The hearts were pumped at 2 normal limits of human heart rate. Full‐volume data were acquired before and after a simulated myocardial infarction (MI) at the 2 most commonly used FRs. LS and CS values were evaluated against sonomicrometry. ResultsLongitudinal strain and CS derived from high FR acquisitions showed statistically superior correlations with sonomicrometry data (LS: R2 = 0.85, CS: R2 = 0.84) than strain values from low FR (LS: R2 = 0.78, CS: R2 = 0.76) (all P

We present a unique case of an anterior ST elevation myocardial infarction as a result of coronary embolism, the source of which appears to be calcific debris from mitral annular calcification (MAC). Although embolic phenomena in the setting of MAC has been documented previously, particularly in the setting of acute ischemic stroke, to our knowledge this is the first reported case in the literature where MAC alone appears to have resulted in a coronary embolic event.

Int J Angiol DOI: 10.1055/s-0039-1695049Myocardial infarction (MI) is one of the leading causes of mortality today both in developed and developing countries alike. Advancement in the pharmacotherapy and revascularization techniques has resulted in drastic improvement in survival. Most of the complications of MI can be managed adequately resulting in reduced mortality from MI in the recent years. However, mortality from stroke following acute MI remains high even today. Here, we discuss the incidence, risk factors, and management of stroke following acute ST elevation MI. [...] Thieme Medical Publishers 333 Seventh Avenue,...

SummaryDespite the prognostic significance of severe aortic valve stenosis, knowledge is limited in the general population. To document the status quo for Austria, knowledge about valvular heart disease/aortic valve stenosis was documented in 1001 participants>60  years of age. 6.7% of respondents were knowledgeable of aortic valve stenosis, with 1.6% being concerned about the condition (24.1% cancer, 18.8% Alzheimer’s disease, 15.1% stroke). 29.5% were familiar with valvular heart disease (76.7% heart attack, 36.9% stroke). Only 1/3 reported auscultatio n by their general practitioner (GP) at least ever...

Abstract The modern way of life contributes to the higher frequency of a complex state medically called metabolic syndrome (MetS), which is an inevitable consequence of several most common diseases of modern civilization. Patients with MetS have three times higher risk of experiencing a heart attack or a stroke and twice higher possibility to die from them. Serbia holds the infamous third place in Europe in mortality from heart disease, just behind Russia and Ukraine. The study explores the correlation of every combination of genotypes of apoE (apolipoprotein E) and LRP1 (low density receptor- related protein 1) g...

Reperfusion injury follows ischemia/reperfusion events occurring during myocardial infarction, stroke, embolism, and other peripheral vascular diseases. Decreased blood flow and reduced oxygen tension during ischemic episodes activate cellular pathways that upregulate pro-inflammatory signaling and promote oxidant generation. Reperfusion after ischemia recruits inflammatory cells to the vascular wall, further exacerbating oxidant production and ultimately resulting in cell death, tissue injury, and organ dysfunction. Diving mammals tolerate repetitive episodes of peripheral ischemia/reperfusion as part of the cardiovascula...

ConclusionCRS is associated with an increased incidence of asthma, AMI, stroke, anxiety disorder, and depression. Therefore, we suggest that clinicians should monitor CRS patients carefully, and optimize management as a means to potentially decrease these other associated comorbid conditions.

Authors: Iyer KS, Dayal S Abstract Platelets are small, anucleated effector cells that play an important role in linking the hemostatic and inflammatory processes in the body. Platelet function is known to be altered under various inflammatory conditions including aging. A gain in platelet function during aging can increase the risk of thrombotic events, such as stroke and acute myocardial infarction. Anti-platelet therapy is designed to reduce risk of serious cerebrovascular and cardiovascular events, but the adverse consequences of therapy, such as risk for bleeding increases with aging as well. Age-associated co...
