Effects of bariatric surgery on cardiovascular risk factors among morbidly obese patients.

AIM OF THE STUDY: The aim of this study was to evaluate the influence of laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric by-pass on risk factors of cardiovascular diseases. MATERIAL AND METHODS: We analyzed prospectively collected data of patients operated for morbid obesity who were qualified for laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric by-pass (LRYGB). Risk factors for wylaczecardiovascular diseases were assessed with the SCORE scale and both full and hard Framingham cardiovascular risk scores (FCRs). The data were collected on admission and one year after the procedures. We enrolled 264 patients (119 females, 116 males, 40.2±9.9 years old), of whom 117 underwent LRYGB and 118 LSG, respectively. RESULTS: Preoperatively, 12% of patients were in the high-risk category of the SCORE scale, 65% were in the moderate risk category, and 24% were in the low-risk category. The median score of the SCORE scale was 1 (1-2). Lipid-based full FCR was 34.5% (24%-68%) and the hard FCR was 17.5% (10%-52%), while the respective BMI-based FCRs were 59% (31%-84%) and 37% (15%-67%). One year after the procedures, the mean %EBMIL (62.88%±20.02%) and %EWL (53.18%±15.87) were comparable between both procedures. Hypertension treatment was not necessary in 33 patients after LSG and in 55 after LRYGB. Diabetes mellitus remitted in 9 and 29 patients, respectively. Both procedures significantly reduced high and moderate risk prevalence in the SCORE scale in favor of the low risk category. Surgical interventions resulted in significant reductions of FCRs 1 year after surgery ( p<0.001). CONCLUSIONS: Both LSG and LRYGB lead to a significant and comparable body mass reduction. Both procedures significantly decrease of the risk of cardiovascular diseases, based on SCORE and Framingham scales.

Comparison of the early effects of out-of-hospital resuscitation in selected urban and rural areas in Poland. A preliminary report from the Polish Cardiac Arrest Registry by the Polish Resuscitation Council.

BACKGROUND: The chain of survival is a set of most important factors affecting survival after an out-of-hospital cardiac arrest (OHCA). Recognising the difficulties in applying the chain is the key to improving outcomes. Early return of spontaneous circulation (ROSC) after a cardiac arrest is a fundamental factor for patient survival. AIM: To assess the degree to which the location of OHCA affects ROSC during resuscitation efforts. METHODS: Emergency medical service (EMS) teams filled cardiac arrest forms based on standard (Utstein) guidelines. The registry covered data from January 2013 to May 2014 collected over the area of 23,706 km2 with the population density of 90 persons/km2. This constitutes 7.6% of the area of Poland. The average population density in Poland is 123 persons/km2. RESULTS: Over the time period covered by the study, 5185 cases of OHCA were reported. Resuscitation was attempted in 2415 (46.6%) cases. ROSC was achieved in 736 (30.48%) cases, including 374 (32.13%) cases in urban areas and 362 (28.94%) cases in rural areas. This difference was not statistically significant. Compared to urban areas, event witnesses in rural areas were more likely to perform bystander resuscitation and receive instructions from the EMS dispatchers. In the whole study group, cardiac disorders were the most common underlying cause of cardiac arrest (70.35%). The median time of ambulance arrival to the scene was significantly shorter in urban areas compared to rural areas (median time 6 min and 12 min, respectively). CONCLUSIONS: No significant relation was found between the location of OHCA and ROSC despite the fact that the time to ambulance arrival was significantly shorter in urban areas. In rural areas, resuscitation was more frequently initiated by the event witnesses. Both in urban and rural areas, OHCA was most commonly due to cardiac causes, and the initial recorded cardiac rhythm was a non-shockable one.
