Reflected radio signals reveal the insides of blood vessels ...

The arterial vasculature is the second most frequently calcified structure in the human body after the skeleton. Calcification of the aorta and aortic valves occurs in most individuals in westernized ...

Abstract: A left-ventricular pumping model based on a left-ventricular systolic time-varying pressure/volume ratio e(t) has been proposed on the basis of the physiological studies indicating that the ...

Abstract: The four stages (first heart sound (S1), systole, second heart sound (S2), and diastole) of heartbeat sounds recorded by contact seismocardiogram (SCG) reflect the health of the heart, but ...

Atrial fibrillation (AF) is characterised by an increased risk of pathological thrombus formation due to a disruption of physiological haemostatic mechanisms that are better understood by reference to ...

Patients with myocardial infarctions may show a paradoxic precordial outward systolic movement that can be recorded by the kineto-cardiographic technic and often is felt at the bedside. Three types of ...

Isolated systolic hypertension is when only the systolic blood pressure is high, while the diastolic remains normal. It is common in adults over 65 and can lead to heart attack or stroke if untreated.

Researchers are uncovering new details about a recently identified heart condition that mimics a major heart attack and can strike otherwise healthy people. It can be triggered by stress or grief.
