The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
In the heart, increased arterial stiffness, increased systolic blood pressure, and widened pulse pressures, all resulting from chronic hypertension, can cause significant damage. Coronary perfusion pressures are decreased by these factors, which also increase myocardial oxygen consumption, possibly leading to left ventricular hypertrophy .
The main cause of cardiac arrest is two types of arrhythmias called ventricular fibrillation or ventricular tachycardia. Other potential causes include: Heart tissue scarring from a previous heart ...
Hypertension or high blood pressure affects at least 26.4% of the world's population. [15] Hypertensive heart disease is only one of several diseases attributable to high blood pressure. Other diseases caused by high blood pressure include ischemic heart disease, cancer, stroke, peripheral arterial disease, aneurysms and kidney disease.
Cardiac arrest is not the same as a heart attack, although almost any known heart condition, including heart attack, can cause cardiac arrest. Another emergency that can lead to cardiac arrest ...
An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. [3] [4] Most MIs occur due to coronary artery disease. [3] Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol intake.
Left ventricular hypertrophy. Hypertensive heart disease is the result of structural and functional adaptations [18] leading to left ventricular hypertrophy, [19] [20] [21] diastolic dysfunction, [18] [20] CHF (Congestive Heart Failure), abnormalities of blood flow due to atherosclerotic coronary artery disease [18] and microvascular disease, [10] [19] and cardiac arrhythmias. [19]
Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body's organs due to the dysfunction of the heart.Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness.
