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. People may also have a severely low blood pressure and heart rate.
While the general signs for all types of shock are low blood pressure, decreased urine output, and confusion, these may not always be present. [6] While a fast heart rate is common, in those on β-blockers , those who are athletic, and in 30% of cases of those with shock due to intra abdominal bleeding, heart rate may be normal or slow. [ 7 ]
Acute decompensated heart failure is a worsening of chronic heart failure symptoms, which can result in acute respiratory distress. [66] High-output heart failure can occur when there is increased cardiac demand that results in increased left ventricular diastolic pressure which can develop into pulmonary congestion (pulmonary edema). [46]
This is suggested by an inappropriately low heart rate in the setting of hypotension. [3] Cardiac contusion and infarctions can result in cardiogenic shock. [3] Finally, other causes should be considered that are not related to trauma or blood loss. In the undifferentiated patient with shock, septic shock and toxic causes are also on the ...
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.
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.
The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and cardiac amyloidosis (in which misfolded ...
Peripheral physical signs of aortic regurgitation are related to the high pulse pressure and the rapid decrease in blood pressure during diastole due to blood returning to the heart from the aorta through the incompetent aortic valve, although the usefulness of some of the eponymous signs has been questioned: [23] Phonocardiograms detect AI by ...
