Results from the meta-regression approach showed an inverse relation between cardiovascular risks and BMI reduction .
Conclusions The present study showed an overall reduction of cardiovascular risk after bariatric surgery .
In summary , our study showed that laparoscopic bariatric surgery is an effective therapeutic option to reduce the cardiovascular risk in severe obese patients
Background This study aims to evaluate the 12–24-month impact of bariatric surgery on the foremost modifiable traditional risk factors of cardiovascular disease .
Laparoscopic Roux-en-Y Gastric Bypass and Its Early Effect on Blood Pressure
Background  Laparoscopic Roux-en-Y gastric bypass ( LRYGB ) surgery  is known to have a significant effect on obesity-related comorbidities such as hypertension curing it in some ( 50–70 % ) while improving control in others . Our aim was to observe the changes in blood pressure ( BP ) in a cohort of 100 patients followed prospect ively for 1 year after LRYGB .  Methods BP measurements were recorded prospect ively in 100 consecutive patients preoperatively and then postoperatively at weeks 1 , 5 , 9 , and months 6 and 12 . In order to reduce bias , three BP measurements were made by the same nurse at each office visit and the mean recorded . Pre- and postoperative usage of antihypertensive medication was also noted . Results Eighty-nine women and 11 men underwent LRYGB and their BP monitored for 1 year . There was an 85 % follow-up rate with mean % excess body weight loss of 60 . Reductions in systolic ( 9 mmHg ) and diastolic ( 7 mmHg ) BP measurements were seen as early as week 1 postoperatively and maintained for the duration of the observation period ( P < 0.05 ) . Furthermore , postoperative usage of antihypertensive medication is reduced to a third of preoperative use . Conclusion  LRYGB  is associated with an early reduction in BP and antihypertensive medication usage which is maintained at 1 year after surgery . This early impact on blood pressure occurs before any significant weight loss is achieved thereby suggesting a hormonal mechanism that may be involved for the changes observed
