[Thrombolysis in acute myocardial infarction in the aged. A greater risk of cardiac rupture?].

OBJECTIVE: To evaluate age group and i.v. thrombolytic therapy (TT) influences on cardiac rupture complicating acute myocardial infarction (AMI). CONCEPTION: Retrospective analysis of patients (pts) admitted during 1988-89 to an Intensive Care Unit of a Terciary Hospital (UCIM) with AMI. POPULATION: 430 pts were admitted with AMI. During this period 89 pts were submitted to TT (25% age greater than or equal to 65 years). Eighty four pts died during hospital stay and 42 had autopsy study (50%). Only 7 of nonautopsied pts died of undetermined cause. Dead pts had age m +/- SD 72 +/- 11 years old (yo) (37% female, 63% male and 74% age greater than or equal to 65 yo). RESULTS: Nineteen pts died of cardiac rupture (CR) (23%). CR prevalence was 1.4% (3/218) in pts less than 65 yo and 7.5% (16/212) in pts greater than or equal to 65 yo (p less than 0.01). CR prevalence in pts submitted to TT (4.5%) 4/89, was similar to pts not submitted to TT (4.4%) 15/341 (n.s.). Pts less than 65 yo had nonsignificant differences in CR wether submitted or not to TT (0% vs 2%). Elderly pts (greater than or equal to 65 yo) CR prevalence was 18% (4/22) in those submitted to TT vs 6% (12/190) in those not submitted to TT (p less than 0.05). CONCLUSIONS: Thrombolytic therapy may carry an additional risk for cardiac rupture in elderly patients (greater than or equal to 65 yo).

[Thrombolysis in acute myocardial infarct. Experience at Santa Maria's Hospital].

OBJECTIVES: To evaluate the experience with i.v. streptokinase (SK) in the treatment of acute myocardial infarction (AMI) in two cardiac care units. Conception: Retrospective analysis of patients (pts) admitted either to UCIM or UTIC-AC with the diagnosis of AMI receiving SK. PATIENTS: 77 pts were treated, although one of them was later proved to be a false positive diagnosis of AMI. Of the other 76, there were 63 men and 13 women with age 55 +/- 12 (mean age +/- SD) years (limits of 20 and 82 years). AMIs were anterior in 42% of the pts, inferior in 51%, anterior and inferior in 4% and non Q wave in 1%; Killip classes (cl) were: cl I in 64%, cl II in 26%, cl III in 5% an cl IV in 5%. The time interval from the beginning of acute symptoms to the arrival at the hospital was 2.8 +/- 1.2 hours (1 to 15) and from that moment to administration of SK was 1.6 +/- 1.4 h. The whole interval to the administration of SK was 4.4 +/- 2.5 h. RESULTS: The 3 criteria of reperfusion (pain relief, ST changes resolution and less than 18 h maximum CK rise) were present in 36% of the pts, 2 of the criteria in 21%, and 41% of the pts had only one or no criteria. The time interval to the administration of SK in these 3 groups was 3.3 +/- 1.3 h, 4.8 +/- 3.1 h and 5.0 +/- 2.5 h respectively. Non fatal complications occurred in 16% of the pts (major bleeding in 2.6%, minor bleeding in 99% and minor anafilaxy in 4%. Mortality was 11.8% (9 pts). Two thirds of the deaths were due to cardiac rupture. In hospital residual ischemia was present in 9% (7 pts). CONCLUSION: Treatment of AMI with i.v. SK proved to be a safe and easy to apply therapeutic option, carrying a low morbidity and mortality, lower than that normally observed in our hospital with the conventional approach of AMI before the era of thrombolysis.

[Doppler echocardiography in the diagnosis of mechanic complications of acute myocardial infarction].

OBJECTIVES: To evaluate the ability of bedside emergency Doppler/Echocardiographic (ECOCG/DP) studies in the diagnosis of mechanic complications during acute myocardial infarction (AMI). DESIGN: Retrospective analysis of 44 fatal AMI cases, studied by ECOCG/DP and with diagnostic confirmation by surgery and/or necropsy. SETTING: Patients (pts) with AMI admitted to an Intensive Care Unit of a tertiary Hospital (UCIM), Hospital de Santa Maria. PATIENTS: 44 fatal AMI cases were analysed (24 men and 20 women; mean age +/- SD: 72 +/- 9 years) and were divided in two groups according to Killip classification in Group 1 (III/IV): 35 pts and Group 2 (I/II): 9 pts. METHODS: ECOCG/DP was performed in a routine basis at admission, using all standard views and by subcostal view when in an emergency scenario. RESULTS: In 20 pts with bad left ventricular function (LVF) (Group 1) at admission, ECOCG/DP monitoring showed that death was due to worsening of LVF, which was confirmed by necropsy. In the other 15 pts of this group, ECOCG/DP documented the clinical diagnosis of cardiac rupture (free wall: 4 pts; papillary muscle: 4 pts; interventricular septum: 7 pts) which was confirmed by surgery and/or necropsy. In the 9 pts of Group 2, ECOCG/DP disclosed, at admission, good LVF in all. In 5 pts there was a sudden worsening clinical status, and ECOCG/DP showed a severe pericardial effusion with right chambers collapse, highly suggestive of free wall rupture also confirmed at necropsy. In the other 4 pts, ECOCG/DP showed aggravation of wall motion abnormalities and of LVF without rupture, once again in agreement with necropsy. Five clinical cases are presented for illustration of this issue. CONCLUSION: In the 44 fatal AMI cases of our study there was complete agreement between the ECOCG/DP and necropsy studies. In AMI patients, ECOCG/DP monitoring can in a routine basis, evaluate wall motion abnormalities and LVF. In an emergency setting ECOCG/DP can diagnose all the mechanic complications with a great certainty.
