[Cardiovascular complications in hypertensive patients during the peroperative phase]
Insights
Inadequate hypertension management during surgery increases cardiovascular risks. Consistent preoperative treatment is crucial for reducing intraoperative and postoperative complications in hypertensive patients.
Area of Science:
- Cardiology
- Anesthesiology
- Public Health
Context:
- Prospective study evaluating circulatory complications in 151 hypertensive patients undergoing surgery.
- Patients categorized into four groups based on hypertension treatment and blood pressure control.
- Focus on intraoperative and postoperative phases of surgical procedures.
Purpose:
- To assess the effectiveness of different hypertension treatment modes on circulatory complications.
- To identify patient groups at higher risk for cardiovascular events during and after surgery.
- To provide evidence-based recommendations for preoperative hypertension management.
Summary:
- Inadequate or short-term hypertension treatment led to the highest complication rates (over 36% in Group 2, 30% in Group 3).
- Patients with normal blood pressure (Group 1) and threshold hypertension (Group 4) had significantly lower complication rates (16%).
- Cardiovascular complications were most frequent in inadequately treated and untreated hypertensive patients.
Impact:
- Highlights the critical need for consistent preoperative hypertension management to mitigate surgical risks.
- Suggests that organizational difficulties should not lead to treatment discontinuation or non-treatment.
- Emphasizes the importance of optimizing blood pressure control in hypertensive patients undergoing surgery.
Abstract:
Circulatory complications during the intraoperative and postoperative phases were evaluated in a prospective study on the effectivity of different modes of treatment of hypertonics. 151 patients were subdivided into four groups: Group 1: Treated hypertension, blood pressure normal Group 2: Treated hypertension, blood pressure levels above 160 mmHg Group 3: Untreated hypertension or treatment of hypertension discontinued Group 4: Patients with threshold hypertension. The results show that patients treated inadequately or for a short period only, had the highest complication rates. On the whole, more than 36% of the patients treated inadequately (group 2) during the intraoperative and postoperative periods, had complications of the cardiovascular system, whereas in the untreated patients (group 3) the rate of complications was 30%. Patients with a normal blood pressure (group 1) and with threshold hypertension (group 4), on the other hand, showed a markedly lower incidence of complications, namely, 16%. These results suggest that it would be advisable to effect a consistent preoperative treatment, thus lowering the involved risk. On no account should any possible difficulties in organizing such treatment result in discontinuance of treatment of in-non-treatment.
