Insights
Left ventricular hypertrophy (LVH) is linked to worse outcomes after coronary artery bypass grafting (CABG). Patients with LVH experienced longer recovery times and higher complication rates following CABG surgery.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Research
Background:
- Left ventricular hypertrophy (LVH) is a common cardiac condition.
- Coronary artery bypass grafting (CABG) is a major surgical procedure for coronary artery disease.
Purpose of the Study:
- To investigate the impact of LVH on early outcomes after CABG surgery.
- To assess the relationship between LVH and post-CABG complications.
Main Methods:
- Prospective cohort study of 82 patients undergoing CABG.
- Patients divided into two groups: with LVH (38) and without LVH (44).
- Comparison of early postoperative outcomes, including recovery time, ventilation duration, ICU stay, and complications.
Main Results:
- LVH patients had longer time to regain mechanical activity (5.76±1.82 min) and mechanical ventilation (16.50±4.25 hours).
- Mean ICU stay was longer in the LVH group (3.81±1.20 days) compared to the non-LVH group (2.56±0.81 days).
- LVH was significantly associated with arrhythmias (p=0.022), infections (p=0.005), and wound infections (p<0.001).
Conclusions:
- LVH is associated with increased morbidity and poorer early outcomes in patients undergoing CABG.
- Presence of LVH indicates a higher risk of complications post-CABG surgery.
Objectives:
To evaluate the relationship between left ventricular hypertrophy (LVH) and coronary artery bypass grafting (CABG) procedure especially on the early outcome during the first 6 months following surgical intervention.
Method:
This prospective cohort study included 82 patients with coronary artery disease indicating CABG. These patients were admitted, operated and followed -up in cardiothoracic surgery departmentsin the faculty of medicine, Kafrelsheikh university hospitals in the period from April 2019 till November 2021.The patients included in this study were divided into two groups according to presence or absence of left ventricular hypertrophy, Group I had 38 (46.34%) patients with LVH and Group 2 had 44 (53 .65%). patients without LVH.
Results:
The time to regain mechanical activity waslonger (5.76±1.82) minutesin LVH patients(p <0.001). LVH group had a significantly longer period of mechanical ventilation 16.50±4.25 hours (p <0.001) compared to non LVH group which was 9.61±3.78 hours. Also, the mean duration of ICU stays in the LVH group compared to the non LVH group was 3.81±1.20 days versus 2.56±0.81 daysrespectively. The ICU follow up showed a statistically significant relationship of arrhythmias with LVH (p =0.022), infections (p =0.005) and wound infections (p<0.001).
Conclusions:
In patients undergoing CABG surgery, LVH has been associated with increased morbidity and poor outcome.
