Cardiac events were divided into three categories: pericardial (symptomatic effusion and pericarditis), ischemia (myocardial infarction and unstable angina), and arrhythmia. Univariable competing risks analysis was used.112 patients were analyzed, with median follow-up 8.8鈥痽ears for surviving patients. ...
the leaflets open to allow blood to move forward to the next chamber. When your heart relaxes, the leaflets close to prevent blood from flowing backward. There are several kinds of valve disease, and you can have the same problem in more than one valve. Examples of heart valve problems...
When the heart's electrical system malfunctions, the normal rhythm of the heart can be affected. Depending upon the abnormality, the heart may begin to beat too fast, too slow, irregularly, or not at all. Heart rhythm disorders are often referred to as cardiac arrhythmias (cardiac = heart;...
Ischemia of the brain tissue (cerebral ischemia) is most often focal meaning that it only affects a part of the brain and not the entire organ. However, it can be global when blood supply to the entire brain is reduced simultaneously and there is no pathology specific to the arteries supply...
We determined whether the exercise electrocardiogram predicted acute cardiac events during moderate or strenuous physical activity among 3617 asymptomatic,...

The NAD(P) + -hydrolyzing enzyme CD38 is activated in the heart during the process of ischemia and reperfusion, triggering NAD(P)(H) depletion. However, the presence and role of CD38 in the major cell types of the heart are unknown. Therefore, we characterize the presence and function of...
CFs account for about 60–70% of all normal cardiac cells and about one third of the volume of the normal heart. CFs produce an extracellular matrix that supports the CMs and participates in post-injury repair by regulating the proliferation and migration of cardiac cells. Ischemia, pressure, ...
In this review, we make an effort to present and discuss the theory that obesity, because of its similarity in changes observed in the aging heart, may accelerate the entire process of cardiac aging and exacerbate the medical effects of elderly those with obesity. concentration. Consequently, it...
To this end, this study introduces a free access dataset of normal peripheral white blood cells called Raabin-WBC containing about 40,000 images of white blood cells and color spots. For ensuring the validity of the data, a significant number of cells were labeled by two experts. Also, the...
