The hearts of patients who died of coronary disease and had myocardial bridges were studied by postmortem coronary angiography, cardioventriculography, and complex pathomorphological analysis. The relationship between the incidence and pathomorphology of myocardial bridges, on the one hand, and the type of blood supply, segmentary topography of the major coronary arteries, geometry of the left ventricle, and coronary changes in different forms of coronary disease, on the other, was analyzed. Diagnostic criteria were developed and the main components of the etiology, patho- and thanatogenesis in coronary patients with coronary arteries not affected by atherosclerosis are presented.

Mechanical circulatory support: when, how, and for whom.

Cardiogenic shock represents a critical condition in which the heart is unable to maintain adequate circulation leading to insufficient tissue perfusion and end-organ failure. Temporary mechanical circulatory support offers the potential to stabilize patients, provide a bridge-to-recovery, provide a bridge-to-decision, or facilitate definitive heart replacement therapies. Although randomized controlled trials have been performed in infarct-related cardiogenic shock and refractory cardiac arrest, the optimal timing, appropriate patient selection, and optimal implementation of these devices remain complex and predominantly based on observational data and expert consensus, especially in non-ischaemic shock.

Background: Direct mechanical ventricular actuation (DMVA) with the Anstadt cup is effective for non-blood-contacting biventricular support. Pneumatic regulation of a silicone device augments ventricular pump function. Vacuum attachment facilitates diastolic augmentation critical for biventricular support.

The cardiac myosin binding protein-C (cMyBP-C) regulates cross-bridge formation and controls the duration of systole and diastole at the whole heart level. As known, mutations in cMyBP-C increase the cross-bridge number and rate of their cycling, hypercontractility, and myocardial hypertrophy. We investigated the effects of the mutations D75N and P161S of cMyBP-C related to hypertrophic cardiomyopathy on the mechanism of force generation in isolated slow skeletal muscle fibers.

Osteoporosis and cardiovascular disease (CVD) share common risk factors and pathophysiological mechanisms, raising concerns about the cardiovascular implications of sclerostin inhibition. Romosozumab, a monoclonal antibody that targets sclerostin, is effective in increasing bone mineral density (BMD) and reducing fracture risk. However, evidence suggests that sclerostin inhibition may adversely affect vascular calcification, potentially increasing the risk of myocardial infarction (MI) and stroke.

We present a case of a 52-year-old male with no known past medical history who presented to an outside hospital with acute chest pain. Initial workup revealed anteroseptal ST-elevation myocardial infarction (STEMI) for which the patient was transferred to our facility for emergent percutaneous coronary intervention (PCI). However, the patient's hospital course revealed numerous confounding pathologies that can also present as STEMI, including transthoracic echocardiogram (TTE) abnormalities consistent with takotsubo cardiomyopathy (TCM) as well as myocardial bridging presenting as post-PCI STEMI in the setting of nitroglycerin use.
