Impact of resuscitation and thrombolysis on mortality rate from acute myocardial infarction

International Journal of Cardiology
R J TrentJ Rawles


Our objective was to estimate the saving of life by thrombolysis and resuscitation in acute myocardial infarction (AMI) before and after hospital admission. We studied all 1516 patients admitted to a Scottish teaching hospital in 1990 and 1992 who had a final diagnosis of AMI, and 311 patients enrolled in the Grampian region early anistreplase trial (GREAT). Cardiac arrest occurred in 250/1516 (16%) hospital patients. Of these, 77 (31%) were discharged alive--a saving of 51 lives per thousand cases. 797 (53%) patients received thrombolysis, of whom 114 (14%) died. Assuming the same relative reduction in mortality as in the second international study of infarct survival (ISIS-2; 23%), 34 lives were saved by thrombolytic therapy, representing 22 lives per thousand cases. Of 311 patients in GREAT, 15 (5%) had prehospital cardiac arrest, with 7 patients surviving to discharge (48%)--a saving of 23 lives per thousand cases. Those patients given domiciliary thrombolysis had a one month mortality of 6.7% (11/163) compared with 12.2% (18/148) for those receiving hospital thrombolysis--a saving of 55 lives per thousand cases for prehospital thrombolysis. This is additional to 28 lives per thousand estimated for thrombolytic therapy in h...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
