2 days ago · Myocardial infarction (MI) refers to tissue death ( infarction) of the heart muscle ( myocardium) caused by ischemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. [22]
5 days ago · In panel D, Time Attenuation Curves (TACs) showing the MBF of the whole myocardium (white curve, 157 mL/min/100 mL), of the ischemic myocardium (yellow curve, 85 mL/min/100 mL), and of the normally perfused antero-septal wall (green curve, 191 mL/min/100 mL).
3 days ago · Chest pain, a common initial symptom in hypertrophic cardiomyopathy (HCM) patients, is closely linked to myocardial ischemia, despite the absence of significant coronary artery stenosis. This ...
1 day ago · Cardiac MRI Findings. Myocardial Infarction. Late gadolinium enhancement (LGE) in a subendocardial or transmural pattern, wall thinning, hypokinesia. Hypertrophic Cardiomyopathy. Asymmetric septal hypertrophy, LGE in areas of fibrosis, left ventricular outflow tract obstruction. Dilated Cardiomyopathy. Dilated ventricles, reduced ejection ...
3 days ago · In the management of MI, transthoracic echocardiogram (TTE) is usually performed to assess ventricular function and wall motion abnormalities. 1 For the work-up of MINOCA, TTE may identify important alternative diagnoses including cardiomyopathy or takotsubo syndrome; however, when the cause of MINOCA is not clear, CMR is recommended since it can aid in the diagnosis of myocarditis, takotsubo ...
5 days ago · Generally, it involves an area in the forward wall of the heart related to the blood distribution of the anterior descending coronary artery, though in other instances the inferior wall or the septum (partition) of the ventricle is involved.
4 days ago · Also important were the remarkable changes in the E a pattern at days 1 and 7 when compared to baseline, reflecting very prominently the reduced myocardium kinetics within the regions supplied by the LAD, particularly the anterior and free wall segments, while the septal and posterior segments remain relatively unchanged.
