Objective To investigate the risk factors,clinical and coronary angiographic characteristics in women less than 50 years with coronary heart disease(CHD).Methods One hundred and twenty-six women less than 50 years were divided into CHD group and non-CHD group according to the result of coronary angiography(CAG).Risk factors,clinical and coronary angiographic characteristics were investigated retrospectively.Results In 6395 cases who were given CAG in the corresponding time period,126(1197%)women were less than 50 years,and 44 cases were confirmed as having CHD by CAG[CHD group,mean age(46.8±3.6)years)].Meanwhile 82 cases were in non-CHD group[mean age(45.4±4.3)years)].The incidence rate of hypertension[77.3%(34/44)vs 26.8%(22/82)],diabetes mellitus[34.1%(15/44)vs 4.9%(4/82)],hyperlipidemia[43.2%(19/44)vs 7.3%(6/82)],family history of CHD[43.2%(19/44)vs 7.3%(6/82)],and risk factors of family history of CHD[52.3%(23/44)vs 12.2%(10/82)]had significant difference between CHD group and non-CHD group(P<0.01).88.6%(39/44)CHD palients were acute coronary syndrome,50.0%(20/44)lesion was one-vessel lesion.Left anterior descending coronary was involved most easily.The degree of calcification was lighter.The type.of lesion was mostly localized and segmented.Conclusions Hypertension,hypedipidemia,diabetes mellitus,family history of CHD,and risk factors of family history of CHD are the major risk faetom in women less than 50 years with CHD. The possibility of CHD is higher when having classical angina and multiple risk faetom.

Objective    To analyze the clinical efficacy of right minithoracotomy approach in the treatment of patients with regurgitation after left-sided valve surgery (LSVS). Methods    The clinical data of 77 patients who suffered tricuspid regurgitation (TR) after LSVS and received surgical treatment in the Heart Center of Henan Provincial People's Hospital from 2012 to 2019 were selected. According to the operation method, the patients were divided into a right minithoracotomy group (n=32), including 13 (40.6%) males, aged 57.3±5.3 years and a median sternotomy group (n=45), including 17 (37.8%) males, aged 55.7±6.6 years. Preoperative and postoperative clinical data of the two groups were compared and analyzed. Results    There was no significant difference in preoperative data between the two groups. There were 24 patients of tricuspid valvuloplasty (TVP) and 8 patients of tricuspid valve replacement (TVR) in the right minithoracotomy group. There were 29 patients of TVP and 16 patients of TVR in the median sternotomy group. The operation time, postoperative hospitalization time, intubation time and ICU stay time of the right minithoracotomy group were shorter than those of the median sternotomy group (P<0.001). The operative bleeding, postoperative drainage in 24 hours, postoperative blood transfusion rate and incision poor healing of the right minithoracotomy group were significantly decreased compared with those of the median sternotomy group (P<0.05). The extracorporeal circulation time between the two groups was not significantly different (P=0.382). The postoperative complications and mortality of the righ minithoracotomy group were significantly lower than those of the median sternotomy group (P<0.05). Conclusion    The procedure of right minithoracotomy access can reduce perioperative morbidity and mortality compared with the median sternotomy, and results in satisfied clinical efficacy.
