Both dopamine and norepinephrine can cause increased myocardial oxygen demand and may aggravate ischemia. This can lead to arrhythmias making it important to titrate to the lowest dose needed to improve tissue perfusion. For patients who are in a low output cardiogenic shock dobutamine may be added to optimize cardiac output (CO).

Accumulation of fluid in the pleural space (particularly right) and pericardial space (effusions) may appear. Thus, while pulmonary edema indicates left-sided heart failure, pleural effusions accompany right-sided heart failure. Pleural effusions can range from 100 ml to well over 1 liter and can cause partial atelectasis of the corresponding lung.

This further increases the myocardial oxygen demand leading to cardiac ischemia and MI. Further insult to the delivery of oxygen to the heart can be caused by hypovolemia/ hypoxia from blood loss, fluid loss, and hypercarbia. Ischemia to the myocardial cells results in cellular dysfunction, death, and apoptosis.

Exacerbation of CCF commonly involves a gradual onset of dyspnea due to ongoing fluid retention, with consequent lung congestion, whilst true acute cardiogenic pulmonary edema is commonly due to an acute ischemic event resulting in cardiac diastolic or systolic dysfunction that is unrelated to acute volume overload.
