While a heart attack refers to death of heart muscle tissue as a result of blood supply loss, cardiac arrest is caused when the heart's electrical system malfunctions. Furthermore, the American Heart Association explains that "if corrective measures are not taken rapidly, this condition progresses to sudden death.
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1] An irregular heart beat and fainting may occur. [1]
Right heart failure was thought to compromise blood flow to the lungs compared to left heart failure compromising blood flow to the aorta and consequently to the brain and the remainder of the body's systemic circulation. However, mixed presentations are common, and left heart failure is a common cause of right heart failure. [59]
In the early stages of heart failure, people might not experience any symptoms. But as heart failure progresses, symptoms may occur one by one or all together—and yes, swollen feet is one of ...
It is somewhere between the state of clinical death and a normal functioning state. Patients supported by methods that certainly maintain enough blood circulation and oxygenation for sustaining life during stopped heartbeat and breathing, such as cardiopulmonary bypass , are not customarily considered clinically dead.
Left untreated, ventricular fibrillation is rapidly fatal as the vital organs of the body, including the heart, are starved of oxygen. As a result, patients in this rhythm will not be conscious or responsive to stimuli. Coma and persistent vegetative state may also result.
Considering that the total cardiac cycle has a duration of one second (for a base heart rate of 60 beats per minute), the probability of impact trauma within the window of vulnerability is 1–3 percent only. [1] The cellular mechanisms of commotio cordis are not fully understood. However, it is widely recognized that it may be related to the ...
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
