ABSTRACT
Objective To analyze the electrocardiogram and treadmill exercise performance in patients with coronary artery myocardial bridge.Methods 176 patients with myocardial bridging diagnosed by coronary angiography were selected in the study.The performance of myocardial bridge electrocardiogram and treadmill exercise of different depth and stenosis was observed.Results Deep in myocardial bridge ischemic ST segment and T wave changes were significantly higher than superficial type (x2 =11.02,P ＜ 0.01).Systolic myocardial bridge Ⅲ grade stenosis of ischemic ST segment and T wave changes were significantly higher than grade Ⅰ and grade Ⅱ (x2 =12.78,P ＜0.01;x2 =24.45,P ＜ 0.01).The positive rate of myocardial bridge deep in the treadmill exercise test was significantly higher than the superficial type.Myocardial bridge Ⅲ grade systolic stenosis,treadmill exercise test positive rate was significantly higher than grade Ⅰ and grade Ⅱ (x2 =9.23,P ＜ 0.05;x2 =6.76,P ＜ 0.01).Conclusion Patients with myocardial bridge have various changes in the electrocardiogram and treadmill exercise,changes in deep in the type and degree of stenosis Ⅲ grade systolic are obvious.
ABSTRACT
PURPOSE: Insulin resistance plays a role in the development of dementia and hypertension. We investigated a possible relationship between cognitive impairment and insulin resistance in elderly Chinese patients with primary hypertension. MATERIALS AND METHODS: One hundred and thirty-two hypertensive elderly patients (>60 years) were enrolled in this study, and assigned into either the cognitive impairment group (n=61) or the normal cognitive group (n=71). Gender, age, education, body mass index (BMI), waist hip ratio (WHR), total cholesterol (TC), triglyceride (TG), C-reactive protein (CRP), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), creatinine (Cr), fasting plasma glucose (FPG), fasting insulin (FINS), homeostasis model of assessment for insulin resistance index (HOMA-IR), systolic blood pressure, diastolic blood pressure, smoking history, atherosclerosis and the proportion of uncontrolled hypertension were compared between the two groups. Multi-factorial logistic regression analysis was performed. RESULTS: No significant differences were found in gender, age, TC, CRP, HDL-C, LDL-C, Cr, BP, smoking history, atherosclerosis and the proportion of uncontrolled hypertension between the two groups. The cognitive impairment group had lower education levels, and higher BMI, WHR, TG, FPG, FINS, and HOMA-IR levels than the control group. Logistic regression analysis revealed the levels of education, BMI, WHR, and HOMA-IR as independent factors that predict cognitive impairment in patients. CONCLUSION: Our study demonstrates that poor education and increased BMI, WHR, and HOMA-IR are independent risk factors for cognitive impairment in elderly patients with hypertension. Insulin resistance plays an important role in the development of cognitive impairment in primary elderly hypertensive patients.

Objective:To explore the relationship among serum neutrophil gelatinase associated lipocalin (NGAL), cystatin C (Cys-C) levels and cardiac, renal function;and diagnostic value of NGAL and Cys-C for early renal damage in aged patients With coronary heart disease (CHD).Methods:According to NYHA cardiac function classi-fication,a total of 84 aged CHD patients Were divided into class I group (n=30),class Ⅱ group (n=28)and classⅢ-Ⅳ group (n=26).Another 31 aged healthy objects Were selected as healthy control group.Serum N terminal pro B-type natriuretic peptide (NT-proBNP),NGAL and Cys-C etc. levels Were measured,and the correlation a-mong serum NGAL,Cys-C levels and cardiac function,estimated glomerular filtration rate (eGFR)Were analyzed. The accuracy of serum NGAL and Cys-C diagnosing renal insufficiency Was evaluated by receiver operator character-istic curve (ROC).Results:Along With NYHA class increased,there Were significant increase in serum levels of NGAL [(36.96±21.23)μg/L vs.(87.80±61.40)μg/L vs.(141.21±92.96)μg/L vs.(198.15±98.46)μg/L] and Cys-C [(0.75±0.64)mg/L vs.(1.40±1.88)mg/L vs.(2.33±2.03)mg/L vs.(3.45±1.81)mg/L]in healthy control group,NYHA I,Ⅱ,Ⅲ-Ⅳ groups,and they Were highest in NYHA class Ⅲ-Ⅳ group,there Was significant difference in serum NGAL level betWeen any tWo groups among the four groups (P0.05). Pearson correlation analysis indicated that serum NGAL and Cys-C levels Were positively correlated With NT-proBNP (r=0.842,0.718,P<0.01 both),and negatively correlated With eGFR (r=-0.689,-0.448,P<0.01 both), and serum NGAL level had closer correlation With NT-proBNP and eGFR.Area under ROC of serum NGAL and Cys-C Were 0.884 and 0.744 respectively in diagnosing renal insufficiency.Conclusion:Serum NGAL and Cys-C lev-els have good correlation With cardiac and renal function in aged CHD patients,Which are sensitive and accurate in-dexes for diagnosing early renal damage.
ABSTRACT
Objective To explore the influence of antidepression therapy on symptom score and quality of life in elderly benign prostatic hyperplasia with depression.Methods A total of 94 elderly patients with benign prostatic hyperplasia and depression were randomly divided into two groups:control group (regular drugs) and therapy group adding citalopram 20 mg,once daily for 3 months.The changes of internatio nal prostate sympeom score (IPSS) symptom score,hamilton depression (HAMD) and scores of short form (36) health survey before and after treatment were compared between the two group.Results After treatment,IPSS symptom score [(10.74 ± 4.72) vs.(16.42±8.09)] was much lower in therapy group than in control group (t=4.16,P＜0.05).Each dimension of quality of life was increased after antidepression treatment [physical function (67.75 ± 9.99) vs.(63.09±7.90),SF-36 role physical (70.90±10.85) vs.(62.81±9.16),bodily pain indices (72.75± 10.59) vs.(63.13 ± 9.47),general health (62.59 ± 9.38) vs.(53.67 ± 7.52),vitality (64.09±8.96) vs.(58.11 ± 7.87),social functioning (71.84 ± 6.87) vs.(64.99 ± 7.21),roleemotional (70.15±9.93) vs.(65.01±9.18),mental health (68.74±8.23) vs.(61.77±7.83),all P＜0.05].Conclusions More attention should be paid to antidepression therapy in the elderly with benign prostatic hyperplasia and depression.
