ObjectiveTo observe the clinical effect of clopidogrel combined with Suxiao Jiuxin Pills on patients with acute coronary syndrome (ACS). MethodsNinety-seven patients with ACS diagnosed between January 2010 and December 2011 were divided into the treatment group (treated with clopidogrel combined with Suxiao Jiuxin Pills) (n=48) and the control group (treated with single clopidogrel) (n=49). One month was regarded as a treatment course. After one month, we observed the clinical effect, heart attacks frequency, ST segment changes and adverse reactions for the patients. ResultsThe total effective rate was 79.2% in the treatment group and was 51.0% in the control group. There was significant difference between the two groups (P<0.05). Heart attacks frequency and ST segment were reduced significantly in both the two groups after treatment (P<0.05). The curative effect in the treatment group was significantly better than that in the control group after treatment (P<0.05). ConclusionClopidogrel combined with Suxiao Jiuxin Pills have a better clinical effect in the treatment of ACS than single clopidogrel.
ObjectiveTo evaluate the association between extent and severity of acute coronary syndrome and uric acid, leukocytes. MethodsA retrospective analysis of leukocytes, platelets, lipids and uric acid levels were performed on 23 patients with acute myocardial infarction (AMI group), 17 patients with unstable angina (UA group), and 17 healthy subjects (controls) between January and December 2010. ResultsIn the three groups (AMI, UA, and Control), the leukocyte count was respectively (10.4±3.2)×109/L, (6.9±2.4)×109/L and (5.4±1.1)×109/L (P<0.05); neutrophil was (7.4±3.2)×109/L, (4.8±2.3)×109/L, and (3.4±0.8)×109/L (P<0.001); and uric acid was (401.4±94.3), (384.1±74.1) and (285.5±76.8) μmol/L, respectively (P<0.001). Multinomial Logistic regression showed leukocyte was a predictor for AMI (OR=1.712, P=0.003), while uric acid was not (OR=1.006, P=0.255), regarding the UA group as the reference. When the control group was using as reference, leukocyte was an independently significant factor for AMI (OR=2.942, P=0.004) and was not a significant factor for UA (OR=1.718, P=0.125); uric acid was a significant factor for AMI and UA (OR=1.027, P=0.016; OR=1.021, P=0.041). ConclusionUric acid may be associated with the chronic development of coronary heart disease, while leukocytes may play a potential role in plaque destabilization and the onset of AMI.
ObjectiveTo investigate the impact of clopidogrel resistance on the long-term prognosis in the elderly with acute coronary syndrome (ACS), as clopidogrel is widely used for secondary prevention in the patients with ACS, while studies on the relationship between clopidogrel resistance and long-term outcome in the elderly with ACS are limited. MethodsThree hundred elderly patients with ACS, aged from 70 to 95, with on average age of (81.3±6.4) years old, receiving clopidogrel (75 mg, once a day) over one month between January 2009 and December 2010 were followed up for major adverse cardiac events (MACE, including cardiac death, non-fatal re-myocardial infarction, angina, ischemia stroke/TIA, acute thrombosis and hemorrhage). Platelet aggregation was measured by light transmission aggregometry using adenosine diphosphate as a stimulus. According to the variation of platelet aggregation, the patients were divided into clopidogrel resistance group (<10%) and non-lopidogrel resistance group (≥10%). The median follow-up was 2 years. A Cox hazard proportional model was used to estimate time to outcome associated with clopidogrel resistance and MACE. ResultsThe incidence of clopidogrel resistance was 24.0% in our study population. Patients with diabetes, renal insufficiency, or a higher body mass index tended to have clopidogrel resistance. Compared with those patients without clopidogrel resistance, there was significantly increased MACE in patients with clopidogrel resistance (37.5%, 22.8%; P=0.032). Additionally, Cox hazard proportional model analysis demonstrated that clopidogrel resistance was an independently risk factor for MACE[HR=2.34, 95% CI (1.07, 4.57), P=0.016]. ConclusionDiabetes, renal insufficiency and high body max index are associated with clopidogrel resistance, which can predict the increased risk of MACE in elderly patients with ACS.
ObjectiveTo explore the association between free fatty acid (FFA) and extent of severity of acute coronary syndrome (ACS). MethodsWe analyzed the clinical data of 93 ACS in-patients treated between July 2014 and May 2015, including 35 with acute ST-elevation myocardial infarction (STEMI), 34 with acute non STEMI (NSTEMI), and 24 with unstable angina (UA). Another 29 in-patients during the same period without coronary heart disease and heart failure and with normal results of electrocardiogram and myocardial damage markers were selected as the control. The statistical analysis of FFA collected within 24 hours after admission was conducted. ResultsThe FFA in the ACS group[(1.08±0.41) mmol/L] was significantly higher than that in control group[(0.51±0.15) mmol/L] (P < 0.01). The FFA in patients with STEMI, NSTEMI, and UA in ACS group was (1.32±0.38), (1.12±0.35, and (0.67±0.10) mmol/L, respectively; the FFA in STEMI and NSTEMI patients was much higher than that in the UA patients (P < 0.05), and the difference between STEMI and NSTEMI patients was not significant (P > 0.05). There were 58 NSTEMI and UA patients evaluated by Grace risk score, in whom 30 had Grace score≥140 with the FFA of (1.12±0.37) mmol/L and 28 had < 140 with the FFA of (0.73±0.17) mmol/L; the difference was significant (P < 0.05). There were 35 STEMI patients evaluated by Killip grade, in whom 16 were Killip I-II with the FFA of (1.17±0.37) mmol/L, and 19 were Killip III-IV with the FFA of (1.45±0.35) mmol/L; the difference was significant (P < 0.05). ConclusionElevated plasma FFA could be associated with ischemic risk and extent of severity of ACS.
ObjectiveTo investigate the effects of rehabilitation exercise on exercise tolerance and cardiovascular risk factors in patients with non-acute coronary syndrome (non-ACS) after interventional therapy.MethodsA total of 102 patients with coronary heart disease and non-ACS in our hospital from December 2018 to June 2019 were selected and randomly divided into a control group (n=51, 30 males and 21 females with an average age of 56.1±4.8 years) and a trial group (n=51, 34 males and 17 females with an average age of 55.1±4.9 years). The control group received routine treatment, while the trial group received regular supervised rehabilitation exercise on the basis of routine treatment. Patients were followed up for 6 months to compare the differences in cardiovascular risk factors (blood pressure, blood lipid, fasting blood glucose), 6-minute walking distance (6MWD), adverse lifestyle changes and treatment compliance between the two groups after treatment.ResultsThe difference of 6MWD between the two groups was statistically significant (P<0.05). In the trial group, 6MWD increased after intervention compared with that before intervention, and the difference was statistically significant (P<0.05). Comparison of total cholesterol (TC), high density liptein cholesterol (HDL-C), low density liptein cholesterol (LDL-C) and fasting blood glucose in the trial group before and after intervention showed statistically significant differences (P<0.05). The differences in TC, HDL-C and LDL-C in the control group before and after intervention were statistically significant (P<0.05). It was statistically significant in dietary compliance rate, smoking cessation rate and alcohol cessation rate between the two groups (P<0.05); the differences in the dietary compliance and drug compliance of the trial group before and after intervention were statistically significant (P<0.05).ConclusionRegular supervised rehabilitation exercise can significantly improve the exercise tolerance and cardiovascular risk factors of non-ACS patients after coronary intervention treatment, so as to improve the quality of life and long-term prognosis of non-ACS patients, which is worthy of clinical application.
Acute coronary syndromes (ACS) are clinical syndromes caused by the instability or rupture of coronary atheromatous plaques. The development and treatment of ACS are closely related to some ocular manifestations. Hypertensive retinopathy, retinal arteriovenous occlusion, diabetes retinopathy, and age-related macular degeneration are associated with a high risk of ACS. Retinal vascular occlusion may be a potential postoperative complication of the percutaneous coronary intervention for ACS. Ocular parameters such as the retinal vascular diameter and density, the blood flow velocity of the ophthalmic artery, and the choroidal thickness are expected to be markers for assessing or predicting the risk of ACS, which are of important value for the prevention of cardiovascular events such as ACS.
