SPECT of cardiac perfusion and blood pools provides ungated 3-dimensional and gated 4-dimensional (4D) datasets of the ventricular myocardium. Modern reconstruction and review software is used to ...

During the early systolic phase, the myocardium initially stretches and then contracts, likely to enhance the force of myocardial contraction. As a result, LV contractility increases at the expense of ...

1 Functional Area of Emergency Medicine, Karolinska University Hospital, 14184, Stockholm Objective There is a paucity of data regarding prognosis in patients with acute versus chronic myocardial ...

VPDs with very short coupling intervals developing during an acute stage of myocardial infarction would predict the development of early cycled reentry, potentially culminating in VF, and requires ...

In this situation with abnormal myocardial relaxation, a reduced diastolic filling period and a lack of atrial contraction compromise LV filling substantially, causing the increase in LA and LV ...

Is there an ideal myocardial perfusion imaging protocol? In order to answer this question and choose a protocol for clinical use, one must understand the characteristics of the available ...

Over the last 50 years, manganese-enhanced MRI (MEMRI) has emerged as a complementary approach enabling intracellular myocardial contrast imaging that can identify functional myocardium through its ...

Simultaneously, it promotes myocardial relaxation by activating ... By refining both contraction and relaxation phases of the heart’s pumping cycle, istaroxime addresses critical shortcomings ...

Contraction inhibitors after 30 weeks have no effect on baby's health, study shows by Amsterdam University Medical Centers Credit: Unsplash/CC0 Public Domain ...

Myocardial infarction (MI) stands as a prominent contributor to global cardiovascular disease (CVD) mortality rates. Acute MI (AMI) can result in the loss of a large number of cardiomyocytes (CMs), ...

The UK economy shrank at the start of 2025, according to official figures which had been expected to show further meagre growth. The Office for National Statistics (ONS) said that output declined ...
