P2.48 Arterial Hypertension as a Prognostic Factor in the Early Evaluation of Patients after Myocardial Revascularization Surgery

Abstract

Objetives

to see the prevalence and clinical evolution of hypertensive patients after myocardial revascularization surgery (MRS) in the Coronary Unit.

Methods

a retrospective study for the evaluation of the characteristics and the evolution, in the Coronary Unit, of 72 patients (pts) that underwent MRS.

Results

the prevalence of AHT before surgery was 88.8%, (61% treated with beta blockers, 51% ACEI, 12% received calcium antagonists and 15% diuretics). From the hypertensive ptes, 60.6% presented AHT during the stay in the ICCU (75.6 % of men and 37.5% of women) (p = 0.004). In the ICCU the pts with AHT were treated with nitroglycerin (NTG) in the 95.6% of the cases. The most frequent cause of early postoperatory complications were the taquiarrithmias and mayor bleedings but we did not find a relation between these complications and AHT in the early postoperatory. Bleeding was found in 24 % of the pts that developed AHT postoperatory vs. 12 % of the pts that did not develop AHT (NS). 32 % of the pts that developed AHT presented taquiarrithmias vs. 12% of the pts that did not developed AHT (NS). Patients were sent home with Beta Blockers in the 95.4 of the cases, with ACEI in the 64% and only the 14 was sent home with CA.

Conclusions

1.AHT has a very high prevalence among pts that has received MRS. 2. AHT was more frequent in previously hypertensive men than in women in the early postoperatory of MRS. 3. AHT was not significantly associated with bleeding or taquiarrithmias. 4. Beta Blockers and ACEI were the drugs prescribed to the pts after the acute phase of MRS in the majority of the cases.
