Indications
The following situations may benefit from this device.
- Cardiogenic shock when used alone as treatment for myocardial infarction. 9-22% survive the first year.
- Reversible intracardial mechanical defects complicating infarction, i.e. acute mitral regurgitation and septal perforation.
- Unstable angina pectoris benefits from counterpulsation.
- Post cardiothoracic surgery—most common and useful is counterpulsation in weaning patients from cardiopulmonary bypass after continued perioperative injury to myocardial tissue.
- Preoperative use is suggested for high-risk patients such as those with unstable angina with stenosis greater than 70% of main coronary artery, in ventricular dysfunction with an ejection fraction less than 35%.
- Percutaneous coronary angioplasty
- In high risk coronary artery bypass graft surgery where cardiopulmonary bypass time was shortened, as well as during intubation period and hospital stay.
- Thrombolytic therapy of acute myocardial infarction.

Famous quotes containing the word indications:
“It is difficult to write a paradiso when all the superficial indications are that you ought to write an apocalypse. It is obviously much easier to find inhabitants for an inferno or even a purgatorio.”
—Ezra Pound (1885–1972)
“You must labour to acquire that great and uncommon talent of hating with good breeding, and loving with prudence; to make no quarrel irreconcilable by silly and unnecessary indications of anger; and no friendship dangerous, in care it breaks, by a wanton, indiscreet, and unreserved confidence.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The indications are that swearing preceded the development of cursing. That is, expletives, maledictions, exclamations, and imprecations of the immediately explosive or vituperative kind preceded the speechmaking and later rituals involved in the deliberate apportioning of the fate of an enemy. Swearing of the former variety is from the lips only, but the latter is from the heart. Damn it! is not that same as Damn you!”
—Ashley Montagu (b. 1905)
