In hypertensive patients, the development of left ventricular hypertrophy seems to increase the risk of cardiovascular death although some antihypertensive agents have been associated with regression in left ventricular hypertrophy. A few studies have evaluated the carvedilol, a new drug having a balanced pharmacology of vasodilatation and beta-receptor blockade, particularly in elderly hypertensive patients. To test its effects on left ventricular hypertrophy, patients with essential hypertension and left ventricular hypertrophy were studied before and at the end of 6 months of therapy with 25 mg of carvedilol daily. Candidates had to have moderate, uncontrolled essential hypertension with echocardiographically documented left ventricular hypertrophy (left ventricular mass index > 130 g/m2 for men and > 110 g/m2 for women). Of 26 patients selected, 4 dropped out. The remaining 22 patients successfully completed 6 months of therapy. The average age was 69 +/- 8 years. Carvedilol caused a significant reduction of mean systolic blood pressure from 175 to 145 mmHg (p < 0.001), of diastolic blood pressure from 102 to 82 mmHg (p < 0.001), of left ventricular mass index from 148 +/- 24 g/m2 (p < 0.003), and a non significant change of the mean heart rate from 78 to 72 beats/min. In our study, carvedilol was well tolerated in patients with essential hypertension and left ventricular hypertrophy.  相似文献

老年高血压病患者左心室肥厚危险因素分析   总被引:1,自引:2,他引:1  
目的 旨在探讨老年高血压病患者伴发左心室肥厚的危险因素。方法 15 5例老年男性高血压病患者分为高血压伴左心室肥厚组(45例)和高血压无左心室肥厚组(110例) ,比较两组患者2 4h血压监测各项指标、纤维蛋白原及血脂等浓度,用多元逐步回归分析,探讨左心室肥厚的可能影响因素。结果 两组患者之间年龄、体重指数、体表面积差异无显著性意义;但高血压病程、2 4h平均脉压、平均收缩压及纤维蛋白原差异有显著性意义;2 4h平均脉压升高可能为左心室肥厚的独立危险因素。结论 高血压伴发左心室肥厚是长期血压控制不良、代谢紊乱等多因素作用的结果,其中,脉压增大者更易出现左心室肥厚。  相似文献

Inhomogeneity of ventricular repolarization as detected by QT dispersion may be a potential leading mechanism of sudden death in hypertensive and normotensive (age related) left ventricular hypertrophy. Aim of this study was to investigate QT dispersion, ventricular arrhythmias, and left ventricular mass index in elderly hypertensive and normotensive patients. Study population consisted of 60 consecutive patients (sex: 34 men/26 women; age: 63 +/- 11 years) with essential arterial hypertension and 48 age and sex-matched control subjects (24 men/24 women; 64 +/- 16 years). Measurements included QTc dispersion, ventricular arrhythmias, and left ventricular hypertrophy. Hypertensive patients had greater left ventricular mass index (P = .006) and higher QTc dispersion (P = .004) than controls. Left ventricular hypertrophy was diagnosed in 57 (31 men/26 women) of all subjects. These patients had higher blood pressure (P < .05), Lown's score (P < .001), and QTc dispersion (P < .001). QTc dispersion and Lown's score were independent predictors of left ventricular mass index (P < .001). Conclusively, QTc dispersion is a strong indicator of left ventricular mass index and might be used in risk stratification of hypertensive and normotensive elderly patients.  相似文献

To determine whether patients with hypertension and especially those with left ventricular hypertrophy have subtle changes in cardiac function, we measured the increase in left ventricular ejection fraction and in systolic blood pressure to end-systolic volume index ratio with exercise in 40 hypertensive patients and 16 age-matched normotensive volunteers. Twenty-two hypertensive patients without hypertrophy had normal end-systolic wall stress at rest and exercise responses. In contrast, the 18 patients with echocardiographic criteria for left ventricular hypertrophy demonstrated a significant increase in end-systolic wall stress at rest compared with normal subjects (69 +/- 16 vs. 55 +/- 15 10(3) x dyne/cm2, p less than 0.05) despite having normal resting left ventricular size and ejection fraction. In patients with left ventricular hypertrophy, the increase in ejection fraction with exercise was less than in the normotensive control subjects (7 +/- 7 vs. 12 +/- 8 units, p less than 0.05), and delta systolic blood pressure to end-systolic volume with exercise was reduced (3.3 +/- 3.8 vs. 8.3 +/- 7.7 mm Hg/ml/m2, p less than 0.05). The hypertensive patients with hypertrophy displayed a shift downward and to the right in the relation between systolic blood pressure to end-systolic volume ratio and end-systolic wall stress compared with control subjects and hypertensive patients without left ventricular hypertrophy. Thus, hypertensive patients with left ventricular hypertrophy by echocardiography and normal resting ejection fraction exhibit abnormal ventricular functional responses to exercise. This finding may have implications in identifying patients at higher risk for developing heart failure.  相似文献

OBJECTIVES: The influence of left ventricular hypertrophy (LVH) on left ventricular synchronicity, and the prevalence of left ventricular dyssynchrony in hypertensive patients with LVH are unknown. The purpose of this study was to determine the influence of LVH on left ventricular synchronicity in hypertensive subjects. METHOD: Tissue Doppler imaging (TDI) was performed in 115 hypertensive and 30 control individuals. Hypertensive patients were divided into a LVH group and a non-LVH group according to the left ventricular mass index (LVMI). Diastolic and systolic asynchrony was determined by measuring the maximal differences in time to peak myocardial systolic contraction (Ts-max) and early diastolic relaxation (Te-max) between any two of the left ventricular segments and the standard deviation of time to peak myocardial systolic contraction and early diastolic relaxation of all 12 segments. RESULTS: Ts-max was greater in both the non-LVH and LVH groups than in controls, (96.68 +/- 26.21 versus 79.30 +/- 25.19 versus 53.20 +/- 15.24 ms, both P < 0.001) and in the LVH group than in the non-LVH group (96.68 +/- 26.21 versus 79.30 +/- 25.19 ms, P < 0.01). Te-max was prolonged in both patient groups, being most advance in the LVH group (67.39 +/- 11.01 versus 57.18 +/- 11.42 versus 46.72 +/- 13.24 ms, both P < 0.001 versus control group and P < 0.001 versus non-LVH group). LVH patients had shown a greater prevalence of both systolic and diastolic asynchrony than non-LVH patients. A Ts-max value greater than 88 ms had 68% sensitivity and 71% specificity for detecting hypertensive patients with LVH. CONCLUSION: Left ventricular systolic synchronicity was impaired in hypertensive patients with LVH. TDI was shown to be useful for the detection of myocardial abnormalities in such patients.  相似文献

Left ventricular hypertrophy (LVH) is supposed to be a useful marker of cardiovascular complications during the course of hypertension. Authors compared the presence of heart failure, left ventricular diastolic dysfunction and chronic atrial fibrillation in hypertensive patients with and without left ventricular hypertrophy defined by echocardiography. Hospital records of 192 hypertensives treated in our medical department during years 1996-1999 were analysed. Left ventricular hypertrophy was defined by echocardiography (Penn convention) as left ventricular mass index > 134 g/m2 in men and > 110 g/m2 in women. Presence of LVH was found in 128 patients (mean age 65.9 years), absence of LVH in 64 patients (mean age 64.8 years). Both groups of hypertensives were matched by demographic parameters, by the presence of hyperlipidemia, by smoking habits. Hypertensive patients with left ventricular hypertrophy were more often treated by ACE inhibitors. There were statistically significant more patients with heart failure, left ventricular diastolic dysfunction and chronic atrial fibrillation in LVH-positive patients than in LVH-negative once. There was also statistically significant lower ejection fraction (50.3 +/- 11.4% vs 56.5 +/- 7.4%) in LVH-positive patients than in LVH-negative once. Left ventricular hypertrophy in patients with hypertension brings usually a complicated course of the disease with a high contribution to the development of chronic heart failure.  相似文献

To observe cardiac changes in spontaneously hypertensive rats (SHR) functionally, the vectrocardiographic approach was tried, applying the Takayasu lead system to rats. This vectrocardiogram (VCG) was shown to be sufficiently good to detect left ventricular hypertrophy (LVH) in SHR. VCG in SHR showed specific features, some of which were left upward deviation of the maximum QRS vector in the frontal plane, an increased magnitude of the maximum spatial QRS vector, and prolongations of such indices as the QRS duration, time to the maximum spatial QRS vector and QT interval with abnormal ST-T changes. The P wave of SHR in the X scalar electrocardiogram, lower and wider than that of Wistar-Kyoto rats may also be a significant feature of LVH in SHR. The angle of the maximum QRS vector in the horizontal plane was not proven to be a suitable index of LVH in SHR. Most of the histometrical findings were closely correlated to blood pressure. Some of the vectrocardiographic findings were significantly correlated both to blood pressure and to some of the characteristic findings of LVH, such as the weights of the heart and the left ventricle and so forth. This experiment also indicated that LVH in SHR was not limited only to quantitative myocardial hypertrophy. It also seemed to be related to reversible or irreversible qualitative changes of coronary arteries or myocardium, such as myocardial fibrosis. This vectrocardiographic method was shown to be useful in obtaining various information about the cardiovascular system in rats, especially in SHR, and it seemed to be helpful for further understanding hypertensive cardiac diseases in humans.  相似文献

To assess the circadian blood pressure (BP) changes in elderly hypertensive patients with left ventricular hypertrophy (LVH), the ambulatory BP was measured noninvasively every 30 minutes for 24 hours in those patients with LVH (n = 15) and without LVH (n = 23), and in normotensive elderly subjects (n = 11). Although the daytime systolic BP (SBP) was comparable in the two hypertensive groups, the nighttime SBP in patients with LVH tended to be higher than in patients without LVH (149.0 +/- 15.1 versus 138.4 +/- 20.1 mm Hg, p less than 0.10). The LV mass index correlated significantly with the nighttime SBP (r = 0.43, p less than 0.01), but not with the daytime SBP (r = 0.24, ns), with clinic SBP (r = 0.14, p = ns) or the SBP after handgrip exercise (r = 0.31, p = ns). The difference in the systolic BP between daytime and nighttime (D-N SBP) in patients with LVH (2.8 +/- 9.4 mm Hg) was significantly less than that in patients without LVH (12.8 +/- 16.0 mm Hg) (p less than 0.02). In addition, the D-N SBP correlated inversely with the left ventricular mass index (r = -0.33, p less than 0.05). It was concluded that hypertension in the elderly with LVH was associated with a diminished nocturnal decline in blood pressure.  相似文献

Summary Ketanserin, a serotonergic S2-receptor antagonist, was used in a prospective study in nine hypertensive patients with ECG criteria of left ventricular hypertrophy (LVH). Echocardiographic measurement with M mode was made after 1 month of placebo, and after 3, 6, and 12 months of ketanserin treatment as monotherapy at a mean dose of 31 mg bid. Ketanserin treatment decreased mean left ventricular mass by 9.3% at 3 months (not significant), by 15.3% at 6 months (p < 0.008), and by 26.2% at 12 months (p < 0.02), with a tendency towards improvement in left ventricular ejection fraction, which was not statistically significant. The study showed a sustained effect upon regression of LVH in hypertensives, with preservation of left ventricular function.  相似文献

OBJECTIVES : Left ventricular hypertrophy and albuminuria have both been shown to predict increased cardiovascular morbidity and mortality. However, the relationship between these markers of cardiac and renal glomerular damage has not been evaluated in a large hypertensive population with target organ damage. The present study was undertaken to determine whether albuminuria is associated with persistent electrocardiographic (ECG) left ventricular hypertrophy, independent of established risk factors for cardiac hypertrophy, in a large hypertensive population with left ventricular hypertrophy who were free of overt renal failure. METHODS : Patients with stage II-III hypertension were enrolled in the study if they had left ventricular hypertrophy on a screening ECG by Cornell voltage-duration product and/or Sokolow-Lyon voltage criteria, and clinic blood pressures between 160 and 200/95-115 mmHg and plasma creatinine < 160 mmol/l. A second ECG and morning spot urine were obtained after 14 days of placebo treatment. Renal glomerular permeability was evaluated by urine albumin/creatinine (UACR, mg/mmol). Microalbuminuria was present if UACR > 3.5 mg/mmol and macroalbuminuria if UACR > 35 mg/mmol. RESULTS : The mean age of the 8029 patients was 66 years, 54% were women. Microalbuminuria was found in 23% and macroalbuminuria in 4% of patients. Microalbuminuria was more prevalent in patients of African American (35%), Hispanic (37%) and Asian (36%) ethnicity, heavy smokers (32%), diabetics (36%) and in patients with ECG left ventricular hypertrophy by both ECG-criteria (29%). Urine albumin/creatinine was positively related to Sokolow-Lyon voltage criteria and Cornell voltage-duration product criteria. In multiple regression analysis, higher UACR was independently associated with older age, diabetes, higher blood pressure, serum creatinine, smoking and left ventricular hypertrophy. Patients smoking > 20 cigarettes/day had a 1.6-fold higher prevalence of microalbuminuria and a 3.7-fold higher prevalence of macroalbuminuria than never-smokers. ECG left ventricular hypertrophy by Cornell voltage-duration product or Sokolow-Lyon criteria was associated with a 1.6-fold increased prevalence of microalbuminuria and a 2.6-fold increase risk of macroalbuminuria compared to no left ventricular hypertrophy on the second ECG. CONCLUSIONS : In patients with moderately severe hypertension, left ventricular hypertrophy on two consecutive ECGs is associated with increased prevalences of micro- and macroalbuminuria compared to patients without persistent ECG left ventricular hypertrophy. High albumin excretion was related to left ventricular hypertrophy independent of age, blood pressure, diabetes, race, serum creatinine or smoking, suggesting parallel cardiac damage and albuminuria.  相似文献

To analyze the adrenergic responses and to compare them between hypertensive patients with and without left ventricular hypertrophy (LVH), left ventricular (LV) fractional shortening (FS) and end-systolic wall stress (ESS) were measured by echocardiography and the inotropic response to the infusion of isoproterenol (0.02 μg/kg/min for 5 min) was studied in 25 hypertensive patients without LVH [H(-)] and 30 hypertensive patients with LVH [H(+)]. LVH was determined by echocardiography. Age, gender, heart rate, systolic and diastolic blood pressures, LV end-systolic and end-diastolic diameters, and FS were matched between the groups. The tests were performed before introduction of antihypertensi ve treatment or 4 weeks after its discontinuation. ESS showed a significant inverse linear relation with FS in all the subjects before isoproterenol infusion. The inotropic response to isoproterenol was measured as the increase of FS corrected for the decrease of ESS (ΔFS/-ΔESS), that is, the slope of the change of the relation between FS and ESS. The change in ΔFS/-ΔESS was significantly smaller (0.49 ± 0.15 cm2/g, mean ± SD) in H(?) than in H(+) patients (1.01 ± 0.57 cm2/g) (p < 0.001). It is concluded that, compared with the H(+) group, adrenergic response is depressed in H (?) patients. This depression might be etioloically related to the phenomenon that LVH did not develop in the H(?) group in spite of the same level of pressure load as in the H(+) group.  相似文献

To assess the reversibility of left ventricular hypertrophy (LVH) during terazosin therapy, we studied changes in LVH as determined by echocardiography and humoral parameters before and after three and 12 months of terazosin monotherapy in ten patients. Blood pressure decreased within four weeks of treatment and the antihypertensive effect was sustained throughout 12 months. Left ventricular mass index decreased significantly from 126 +/- 22 g/m2 to 109 +/- 24 g/m2 and 98 +/- 23 g/m2 after 3 and 12 months respectively. Interventricular septum (11.2 to 9.8 and 9.0 mm) and posterior wall thickness (10.4 to 9.6 and 8.8 mm) also decreased significantly, whereas left ventricular internal dimensions were unchanged. Total peripheral resistance decreased significantly after initiation of treatment, but cardiac output did not change. Plasma volume, plasma renin activity and plasma noradrenaltine levels were unchanged by terazosin. Thus, terazosin monotherapy reversed LVH associated with decreased peripheral resistance. It is suggested that the reversal of LVH by terazosin is mainly due to the reduction in ventricular afterload and that humoral factors are not involved in its mechanism.  相似文献

BACKGROUND: Whether the typical electrocardiographic (ECG) strain pattern (Strain, in leads V5 and/or V6), which is associated with left ventricular hypertrophy (LVH) and LV systolic dysfunction, is independently associated with LV diastolic dysfunction is unknown. METHODS: The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study enrolled hypertensive patients with ECG-LVH, of whom 10% underwent Doppler echocardiography. LV diastolic function measures included peak mitral E and A wave velocities and their ratio (E/A); E wave deceleration time (EDT); atrial filling fraction (AFF); and isovolumic relaxation time (IVRT). Normal filling pattern was defined by E/A < 1 with EDT >or= 150 and or=60 ms; abnormal relaxation by E/A < 1 with EDT > 250 ms or IVRT > 100 ms; pseudonormal filling pattern by E/A >or= 1 associated with IVRT > 100 ms or EDT > 250 ms; restrictive pattern by E/A >or= 1 with IVRT < 100 ms and EDT < 250 ms. A combined index of LV systolic-diastolic function was also computed (isovolumic time/ejection time, modified myocardial performance index). Of LIFE echo substudy participants with all needed ECG and Doppler data (n = 791), 110 (14%) had Strain. RESULTS: Strain was associated with male gender, African-American race, diabetes, history of coronary heart disease (CHD), higher systolic blood pressure (BP), LV mass and relative wall thickness, and higher prevalences of echo-LV hypertrophy and wall motion abnormalities, and with slower heart rate (all P < 0.05). Age, diastolic BP and LV ejection fraction were similar in patients with or without Strain. Diastolic parameters, and prevalences of different LV filling patterns, did not differ significantly between patients with versus those without Strain (all P > 0.1), but modified myocardial performance index was higher with Strain (P < 0.05). Findings were consistent in multivariate analyses. The association of Strain with higher modified myocardial performance index was no longer statistically significant after accounting for LV systolic function and wall motion abnormalities. CONCLUSIONS: In hypertensive patients with ECG-LVH, the ECG Strain pattern did not identify independently those with more severe LV diastolic abnormalities.  相似文献
