what are the causes of decreased cardiac output?

Conditions like myocardial infarction, hypertension, valvular heart disease, congenital heart disease, cardiomyopathy, heart failure, pulmonary disease, arrhythmias, drug effects, fluid overload, decrease fluid volume, and electrolyte imbalance are considered the common causes of Decreased Cardiac Output.

Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure.

Blood pressure increases with increased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and rigidity of vessel walls. Blood pressure decreases with decreased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and elasticity of vessel walls.

Several conditions can lead to poor circulation. The most common causes include obesity, diabetes, heart conditions, and arterial issues.

During inspiration, the negative intrathoracic pressure causes pooling of blood in expanding pulmonary vessels and a delay of flow to the left ventricle. Thus, systolic pressure falls as cardiac output falls momentarily. The following procedure checks for a paradoxical pulse.

This is because a dangerously low blood pressure affects oxygen levels and blood flow. Kidney failure, heart dysfunction, respiratory failure, and multiple organ failure are all complications of sepsis and septic shock, notes Brown.

If the heart valve leak is severe, it may impair the forward flow of blood. This can cause symptoms of congestive heart failure, which include: Shortness of breath, especially with exertion or when lying flat. Leg swelling or fluid retention elsewhere in the body.

Causes. Common causes of decreased urine output include: Dehydration due to vomiting, diarrhoea or fever, and a simultaneous lack of adequate fluid intake. Total urinary tract obstruction, such as may result from an enlarged prostate.

Blood pressure varies from one person to another. A drop as little as 20 mmHg, can cause problems for some people. There are different types and causes of low blood pressure. Severe hypotension can be caused by sudden loss of blood (shock), severe infection, heart attack, or severe allergic reaction (anaphylaxis).

Ventricular tachycardia that is prolonged can result in low cardiac output, low blood pressure, and fainting (syncope).

Heart problems: Among the heart conditions that can lead to low blood pressure are an abnormally low heart rate (bradycardia), problems with heart valves, heart attack and heart failure.
