In most cases, a lack of oxygen to your heart, usually from a heart attack, damages its main pumping chamber, the left ventricle. Without oxygen-rich blood circulating to that area of your heart, the heart muscle can weaken and progress into cardiogenic shock.
Rarely, damage to your heart's right ventricle, which sends blood to your lungs to receive oxygen, leads to cardiogenic shock. Damage to the right ventricle hinders your heart's ability to pump blood to your lungs, depriving your body of adequate oxygen.
Other possible causes of cardiogenic shock include inflammation of the heart muscle (myocarditis), infection of the heart valves (endocarditis), weakened heart from any cause, drug overdoses or poisoning with substances that can affect your heart's pumping ability.
