Cardiac symptoms of heart failure include chest pain/pressure and palpitations.Common noncardiac signs and symptoms of heart failure include loss of appetite, nausea, weight loss, bloating, fatigue, weakness, low urine output, waking up at night to urinate, and cerebral symptoms of varying severity, ranging from anxiety to memory impairment and confusion.
Junctional rhythms (if a bradycardia) can cause decreased cardiac output. Therefore, the person may exhibit signs and symptoms similar to other bradycardia such as lightheadedness, dizziness, low blood pressure, and fainting. This rhythm can usually be tolerated if the rate is above 50 beats per minute. [citation needed]
Tissue hypoxia from low oxygen delivery may be due to low haemoglobin concentration (anaemic hypoxia), low cardiac output (stagnant hypoxia) or low haemoglobin saturation (hypoxic hypoxia). [79] The consequence of oxygen deprivation in tissues is a switch to anaerobic metabolism at the cellular level.
Symptoms may include shortness of breath, weakness, or altered mental status. Low blood pressure and tachycardia are often seen in shock. Other symptoms depend on the underlying cause. [4] The physiology of obstructive shock is similar to cardiogenic shock. In both types, the heart's output of blood (cardiac output) is decreased.
Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness. People may also have a severely low blood pressure and heart rate. Causes of cardiogenic shock include cardiomyopathic, arrhythmic, and mechanical. Cardiogenic shock is most commonly precipitated by a heart attack ...
Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease , and heart attacks . [ 4 ]
The classic symptoms include a slow heart rate due to loss of cardiac sympathetic tone and warm skin due to dilation of the peripheral blood vessels. [20] This term can be confused with spinal shock which is a recoverable loss of function of the spinal cord after injury and does not refer to the hemodynamic instability.)
Cardiorenal Syndrome is characterized by the dysfunction of both the cardiac and renal systems, resulting in a range of clinical manifestations. Many patients will have volume overload and therefore may show clinical signs such as jugular venous distension, generalized swelling of the abdomen and/or the lower legs, and difficulty breathing.
