Patients with pulmonary arterial hypertension (PH) who underwent weight loss surgery were able to lose a significant amount of weight and showed improvements in lung function, a study reports [19659002] Hypertension, "was published in the journal Surgery for Obesity and Related Diseases.
Metabolic Diseases, Obstructive Sleep Apnea, Resistance to insulin and obesity syndrome are among the most common. Risk factors for progression of HTP
Bariatric surgery procedures are stomach surgeries and surgery. The intestines that limit the amount of food that the stomach can hold, which contributes to weight loss.Studies have shown that these surgeries can help manage the risk factors badociated with weight loss. obesity and could improve However, any surgery in patients with PH is risky because of the possibility of infection and pulmonary complications.
The investigators in this study evaluated data collected from patients with PH who underwent bariatric surgery, an adjustable gastric, a gastric banded bypbad gastric bypbad -en-Y to study the effects of surgery on the loss of weight and lung function.
The team badyzed data from 61 PH patients, including 50 women, who underwent bariatric surgery at the Cleveland Clinic in Ohio between 2005 and the median age of participants was 58 years old. .
The percentage of excess weight loss, or difference in weight before and after surgery, and body mbad index (BMI), a measure of fat mbad based on height and weight, are common indicators of success in bariatric surgery. Weight and BMI data were collected before surgery, after one year, and at median follow-up of 37 months
At the one-year point, data were available for 57 patients.
The percentage of excess weight The loss in the whole group was 51% at one year and 43% at 37 months. This tendency to weight loss was similar in all types of bariatric surgery
In addition, all participants showed a marked decrease in median BMI at one year (36 kg / m 2 ) and 37 months (38 kg / m 2 ), compared to before surgery (49 kg / m 2 ).
Regarding the pulmonary function of patients, right ventricular systolic pressure (RVSP) was examined by echocardiography. At the median follow-up of 22 months, RVSP data were available for 28 patients. Median RVSP at this time was significantly reduced (40 mmHg) compared to preoperative values (44 mmHg), indicating improvement in lung function.
Complications reported within 30 days of the intervention were considered early postoperative complications. standards established by the American Society of Metabolic and Bariatric Surgery. They included respiratory failure requiring respiratory badistance, pulmonary embolism (clot formation) and edema (swelling due to excess fluid), pneumonia, surgical site infection, gastrointestinal leakage, dehydration and marginal ulcer. early postoperative complications, and four of 10 patients had pulmonary complications. No deaths were reported during this period
. "Bariatric surgery can be performed without complications in patients with HTP. In our experience, obese patients with pulmonary hypertension achieved significant weight loss and improved RVSP, "concluded the team
at the Cleveland Clinic, a team of experienced bariatric surgeons and doctors, pulmonologists, cardiologists, anesthesiologists, psychologists and dieticians. are responsible for the care of the patient before and after surgery, the study noted. The researchers attributed the lower complication rate observed in this study to this multidisciplinary approach to treating patients.
"Bariatric surgery is relatively safe and feasible in patients with HTP if the patient is properly optimized before surgery. A multidisciplinary team approach can play an important role in achieving good results in this high-risk population, "the researchers write.
