Introduction
The effect of cardiovascular disease (CVD) prevention measures aimed at elderly patients requires further evidence. We investigated the effect of statin treatment (targeted to achieve guideline goals) on CVD outcomes in different age groups to determine whether statins are more beneficial in the elderly.Material and methods
The primary endpoint of this post hoc analysis of the GREek Atorvastatin and Coronary-heart-disease Evaluation (GREACE) study (n = 1,600 patients with established coronary heart disease (CHD), mean follow-up 3 years) was the absolute and relative CVD event (a composite of death, myocardial infarction, revascularization, unstable angina, heart failure and stroke) risk reduction in age quartiles (each n = 200). Patients on “structured care” with atorvastatin (n = 800) followed up by the university clinic and treated to lipid goal were compared with the corresponding quartiles on “usual care” (n = 800) followed up by specialists or general practitioners of the patient''s choice outside the hospital.Results
In the elderly (mean age 69 ±4 and 70 ±3 years in the “structured” and “usual care”, respectively) the absolute CVD event reduction between “structured” and “usual care” was 16.5% (p < 0.0001), while in the younger patients (mean age 51 ±3 years and 52 ±3 years in the “structured” and “usual care”, respectively) this was 8.5% (p = 0.016); relative risk reduction (RRR) 60% (p < 0.0001) vs. 42% respectively (p = 0.001). The elderly had higher rates of chronic kidney disease and higher uric acid levels, plus an increased prevalence of diabetes, metabolic syndrome and non-alcoholic fatty liver disease. These factors might contribute to the increased CVD risk in older patients.Conclusions
All age groups benefited from statin treatment, but the elderly on “structured care” had a greater absolute and relative CVD risk reduction than the younger patients when compared with the corresponding patients assigned to “usual care”. These findings suggest that we should not deprive older patients of CVD prevention treatment and lipid target achievement. 相似文献5.
Nitric oxide (NO) exerts important vasodilatory, antiplatelet, antioxidant, antiadhesive, and antiproliferative effects. Although endothelium derived NO has been shown to be of prime importance in cardio- and vasculoprotection, until recently little was known about the role of platelet-derived NO. New evidence suggests that NO synthesized by platelets regulates platelet functions, in particular suppressing platelet activation and intravascular thrombosis. Moreover, platelet NO biosynthesis may be decreased in patients with cardiovascular risk factors or with coronary heart disease, and this may contribute to arterial thrombotic disease in these patients. Here, we review the current state of knowledge as regards the role of platelet-derived NO, both in normal physiology and in cardiovascular disease states, and compare platelet NO signaling and regulation with that in endothelial cells. 相似文献

Asymmetric dimethylarginine (ADMA) is a robust marker of endothelial dysfunction in patients with essential hypertension. We investigated ADMA levels and their association with vascular damage in untreated hypertension. We enrolled consecutive patients with untreated, recently diagnosed hypertension and age‐matched normotensive individuals. 24‐hour blood pressure, central hemodynamics, and arterial stiffness were recorded. A total of 311 individuals were studied: 165 with essential hypertension, 50 with masked hypertension, 25 with white‐coat hypertension, and 71 normotensive individuals. ADMA levels significantly correlated with aortic augmentation index (AIx75) (r = .156, P = .006), aortic pulse pressure (r = .153, P = .007) and marginally with carotid‐femoral pulse wave velocity (r = .110, P = .051), as well as with diastolic office BP. In the multivariate model, aortic AIx75 and age were the only statistically significant predictors of ADMA. This is the largest study to document an independent association between ADMA and aortic AIx75 but not with other indices of arterial stiffness. 相似文献

Cardiac involvement is common in rheumatoid arthritis. Subendocardial viability ratio (SEVR) is a non-invasive measure of microvascular coronary perfusion, yet it remains unclear whether it is affected in rheumatoid arthritis patients. We additionally sought predictors of SEVR in rheumatoid arthritis among a wide range of disease-related parameters, cardiac and hemodynamic factors, and markers of atherosclerosis, arteriosclerosis, and endothelial dysfunction. SEVR was estimated in rheumatoid arthritis patients and healthy controls by applanation tonometry, which was also used to evaluate arterial stiffness (pulse wave velocity and augmentation index). In the rheumatoid arthritis group, carotid intima–media thickness (cIMT) was additionally estimated by ultrasound, cardiac and hemodynamic parameters by impedance cardiography, and endothelial dysfunction by measurement of asymmetric dimethylarginine (ADMA). In a total of 122 participants, SEVR was lower among 91 patients with rheumatoid arthritis compared to 31 controls (141.4 ± 21.9 vs 153.1 ± 18.7%, p = 0.009) and remained so among 29 rheumatoid arthritis patients without hypertension, diabetes, or cardiovascular diseases, compared to the control group (139.7 ± 21.7 vs 153.1 ± 18.7%, p = 0.013). SEVR did not significantly correlate with arterial stiffness, cIMT, ADMA, or disease-related parameters. Multivariate analysis revealed gender (p = 0.007), blood pressure (p = 0.028), heart rate (p = 0.025), cholesterol levels (p = 0.008), cardiac index (p < 0.001) and left ventricular ejection time (p = 0.004) as independent predictors of SEVR among patients with rheumatoid arthritis. Patients with rheumatoid arthritis exhibit lower values of SEVR compared to healthy individuals. Cardiac and hemodynamic parameters, rather than functional indices of endothelial and macrovascular dysfunction, may be useful as predictors of myocardial perfusion in rheumatoid arthritis. 相似文献

BackgroundPatients with heart failure and underlying ischemic heart disease (IHD) exhibit both endothelial dysfunction and increased arterial stiffness. We investigated whether this is also the case in heart failure of nonischemic etiology.Methods and ResultsEleven patients with heart failure and IHD, 12 patients with heart failure from angiographically verified idiopathic nonischemic dilated cardiomyopathy (DCM), and 16 healthy subjects of similar age and sex were compared. Endothelium-dependent and independent function were evaluated by ultrasonic measurement of flow-mediated dilatation (FMD) and glyceryl trinitrate (GTN)-induced dilatation of the brachial artery respectively. Vascular compliance was assessed by carotid-femoral pulse wave velocity (PWV) and augmentation index (AIx). Heart failure severity was similar in IHD and DCM patients. FMD was impaired in the subjects with IHD as compared with control subjects (4.8 ± 0.3 vs. 8.0 ± 3.6 %, P < .01), but not in those with DCM. GTN-induced vasodilatation was not different in patients and controls. PWV was also increased in IHD patients compared with controls (12.1 ± 3.6 vs. 8.0 ± 1.6 m/s, P < .01), but not in DCM patients. AIx was similar in patients and controls.ConclusionHeart failure of nonischemic etiology is not associated with abnormalities of endothelium-mediated dilatation or of arterial compliance. The findings of our study now need to be confirmed in larger studies. 相似文献
