| Background:Coronary heart disease (CHD) deaths of women are the most single disease. In the past 20 years, male mortality rates to decline in coronary heart disease, while women did not get attention. Our main objective is the study of coronary heart disease, coronary heart disease in the know on gender differences in diagnosis to clinical practice and future research to identify the field.Methods: The subjects are the patients at our hospital inpatient medical heart and accept the 410 cases of patients with CAG, in January 2008 ~ December 2008 ,include of 267 cases of men,and 143 cases of women. Divided into two groups by sex, using a retrospective analysis of cases of comparative analysis of two cases of clinical data, risk factors, clinical symptoms, ECG and CAG data. ECG ST segment changes in mean levels or down ramps type≥0.05mv or standard parts lead T-wave inversion, or ST-segment elevation 1 ~ 3 mm. Coronary angiography (CAG) change refers to stenosis <50% of normal or mild stenosis,≥50% stenosis as significant.Results: Incidence of age: larger in women than in men between 40 and-49-year-old male high incidence rate than women (11.9% vs24.0%), 50-59 years old the same (37.1% vs37.1%), 60-year-old women over more than men ( 47.6% vs36.3%), and there was a significant difference (P <0. 05); the seriousness of: Clinical diagnosis of the stability of unstable angina and non-ST-segment elevation myocardial infarction in women than in men patients more (respectively, 16.1% vs7.5%; 47.6% vs37.5%; 22.4% vs1.1%), men diagnosed with acute ST-segment elevation myocardial infarction and old myocardial infarction than women of the probability of high (respectively 22.4% vs36.3%, 4.2% vs9.4%), there was a significant difference (P < 0.05); associated diseases: hypertension, diabetes and hyperlipidemia high ratio of women than men (respectively 63.5% vs52.7%; 28.7% vs19.0%; 29.6% vs17.3%), there was a significant difference sex (P <0.05); smokers: female significantly less than men (10.4% vs67.7%); clinical characteristics: women shown palpitation, shortness of breath, nausea or vomiting and the risk of shoulder pain radioactive than men, and men show more profusely. And dizziness, headache symptoms no significant gender differences. Clinical performance and in line with the rate of inspection: both clinical symptoms and ECG changes and coronary angiography in patients with no gender differences (65.7% vs61.4%); the only clinical manifestations, without coronary angiography and ECG changes and clinical manifestations and ECG changes, no changes in coronary angiography in patients with more female patients (9.1% vs6.0%; 10.5% vs4.5%), there was a significant difference (P <0.05); clinical manifestations and changes in coronary angiography, without ECG changes in patients with more men (16.9% vs11.2%), there was a significant difference (P <0.05); women's single vessel disease than men ( 35.7% vs30.0%), multi-vessel disease more men (23.2% vs 11.2%), there was a significant difference (P <0.05); lesion location: women and men located in LAD, and men more than women, the smallest probability of LM lesions, LCX and RCA was no significant difference between. Stenosis: men in the LM and LAD stenosis significantly more than women (respectively 4.9% vs 2.8%; 57% vs 47.6%), and in the LAD and RCA in the normal or mild stenosis in women than in men (respectively 20.3% vs9.0%; 12.6% vs7.9%), the differences were significant. Muscular bridge was particularly prevalent in the LAD, there is no gender difference in this regard, while the LAD on the bridge more muscle in the male (4.5% vs 2.1%). PCI line treatment of men more (55.8% vs46.2%), there was a significant difference.Conclusion:Female CHD patients with atypical angina, accompanied by many symptoms, and less coronary artery disease, occurred in many postmenopausal women, electrocardiogram in patients with CHD for women must have the diagnosis of the narrow-minded. |
