Key result
Arterial counterpulsation in six patients with massive myocardial infarction in a "pre-shock" condition resulted in 0 in-hospital deaths, despite a predicted mortality risk >50%.
Why the study?
Does arterial counterpulsation improve survival and relieve complications in patients with massive myocardial infarction in a pre-shock condition?

Does arterial counterpulsation improve survival and relieve complications in patients with massive myocardial infarction in a pre-shock condition?
Arterial counterpulsation successfully prevented in-hospital mortality and relieved complications in a small cohort of patients with massive myocardial infarction and impending cardiogenic shock.
Answers are grounded in this paper and cite their sources.
May support arterial counterpulsation in pre-shock MI; leaves open efficacy pending randomized trials.
Six patients with massive myocardial infarction in a “pre-shock” condition were treated with arterial counterpulsation. Prognostic Indices Indicated a mortality risk greater than 50%. Counterpulsation was continued for an average of 5·7 days. Complications of infarction were relieved within four days and were subsequently controlled after cessation of mechanical assistance. There were no deaths In hospital and all patients were ambulant and welt when discharged, on an average of 26 days after admission to hospital.

O’Rourke et al. (1974) conducted a case report in Massive myocardial infarction in a "pre-shock" condition (n=6). Arterial counterpulsation was evaluated on In-hospital mortality. Arterial counterpulsation in six patients with massive myocardial infarction in a "pre-shock" condition resulted in 0 in-hospital deaths, despite a predicted mortality risk >50%.
