From the Research
The target systolic blood pressure (SBP) after left ventricular rupture repair should be maintained at or below 120 mmHg, as suggested by the study 1, which found that control of systolic blood pressure (< or = 120 mm Hg) with beta-adrenergic blocking agents as tolerated contributed favorably to the initial outcome of patients with left ventricular free wall rupture.
Key Considerations
- The goal of maintaining a lower SBP is to reduce stress on the ventricular repair site and minimize the risk of suture line disruption or recurrent rupture.
- A combination of intravenous antihypertensives and negative inotropes like beta-blockers can be used to achieve this target, with careful fluid management to avoid volume overload.
- Afterload reduction with ACE inhibitors may be initiated once the patient is hemodynamically stable, typically 24-48 hours post-repair.
- Frequent assessment of urine output, mental status, and cardiac function is necessary to balance blood pressure management with maintaining adequate end-organ perfusion.
Relevant Evidence
- The study 1 provides evidence for the importance of blood pressure control in patients with left ventricular rupture, with a focus on maintaining SBP at or below 120 mmHg.
- Other studies, such as 2, 3, 4, and 5, provide additional context on blood pressure management and its impact on cardiac function, but the study 1 is the most directly relevant to the question of target SBP after left ventricular rupture repair.
