改善血糖控制可减少糖尿病患者的心血管并发症,不同药物的作用机制不同,其对心血管结局的影响不同.此外,继2007年对罗格列酮潜在心血管风险的认识之后,陆续开展了大量的前瞻性、随机、对照研究,评估降糖药物对糖尿病患者的心血管系统的影响.传统药物中二甲双胍及噻唑烷二酮类药物对糖尿病患者的心血管系统具有保护作用,但必须警惕噻唑烷二酮类药物可增加心力衰竭的风险;第二代及第三代磺脲类促泌剂及非磺脲类促泌剂并不增加患者心血管事件的发生风险.新型药物中并没有看到二肽基肽酶4抑制剂对心血管系统具有有利或不良影响,是否增加心力衰竭风险目前结果并不统一.而胰高血糖糖素样肽-1受体激动剂及钠-葡萄糖协同转运蛋白2可减少糖尿病患者的心血管疾病风险并降低死亡率;但由于数据有限,仍需要更广泛的研究加以证实. 相似文献

心血管系统维持着机体正常的生命活动,心血管系统衰老可引发高血压、动脉粥样硬化、心力衰竭、心肌梗死等疾病。自噬是一种溶酶体依赖性降解途径,其水平随着年龄增加而逐渐降低,一方面提高机体自噬可延缓细胞和组织衰老,另一方面自噬水平的过度激活可诱导细胞自噬性死亡、加速衰老。某些天然药物活性成分能调节自噬,并改善心血管系统衰老。它们可能是通过调节细胞自噬发挥对心血管系统衰老的保护作用。因此,文章就自噬在天然药物活性成分延缓心血管系统衰老中的作用及研究进展进行综述。 相似文献

beta-Adrenergic blockade represents a major pharmacologic advance. These drugs bind to membrane adrenergic receptors interfering with the effects of endogenous catecholamines. Eight beta-blockers are available in the United States, and others are being studied. The drugs have varying pharmacodynamic properties that may modify certain side effects: beta 1-selectivity, partial agonism, alpha-adrenergic blocking activity, membrane stabilization, and varying pharmacokinetic characteristics. The drugs have been shown to be relatively safe and useful for a wide variety of cardiovascular and noncardiovascular disease states, and their wide spectrum of therapeutic activity illustrates the importance of the sympathetic nervous system in the pathophysiology of medical illness. 相似文献

The introduction of β-adrenergic-blocking drugs into clinical medicine in the early 1960s represented a major advance in pharmacotherapy. The use of these drugs highlighted the importance of the sympathetic nervous system in contributing to the pathophysiology of a wide variety of cardiovascular and noncardiovascular disorders. This article summarizes the history of β-blocking agents and reviews the applications of this therapeutic class. These drugs may be useful as primary protection against cardiovascular morbidity and mortality in hypertensive patients and have proved to be beneficial in other cardiovascular conditions. Not all β-blockers have the same mechanism of action and, among them, there are pharmacologic differences that may be of clinical importance. 相似文献

It has become apparent that noncardiovascular drugs can affect blood pressure (BP) in an off‐target manner, either by raising or lowering pressure or by negating the beneficial hypotensive effect of concomitantly prescribed antihypertensives. This paper presents compelling evidence that ambulatory blood pressure monitoring (ABPM) should be used to detect BP effects during the development of noncardiovascular drugs. The requirements for standardizing ABPM to obtain the most information from the least number of participants and the many advantages of obtaining a 24‐hour BP profile are discussed. The use of ABPM in trials of antihypertensive agents, though differing in purpose (the demonstration of BP‐lowering efficacy) from the use of ABPM in trials of noncardiovascular drugs (the demonstration of any off‐target effect on BP) nonetheless provides methodological similarities that can be applied in both contexts with advantage. The paper also considers whether there are lessons to be learned from a regulatory science approach that is designed to prospectively identify unacceptable off‐target cardiac effects of noncardiac drugs and offers some thoughts on how a future paradigm of standardized use of ABPM to assess off‐target BP effects during the development of noncardiovascular drugs might benefit patient safety. 相似文献

Many patients suffer from both heart and lung diseases. The choice of medical drugs should not only be driven by the clinical and prognostic effects on the target organ but should also be selected based on the effects on the respective other organ. Beta blockers and statins have both beneficial and harmful effects on the respiratory system. Angiotensin-converting enzyme (ACE) inhibitors and amiodarone can cause severe lung damage. Low-dose thiazides and calcium antagonists are first-line medications in hypertensive asthma patients but beta blockers should be avoided. Theophyline should be used with caution in patients with known cardiac disease. Glucocorticosteroids can cause cardiovascular symptoms while the phosphodiesterase inhibitor roflumilast appears to have no relevant cardiovascular side effects. Anticholinergic drugs have both favorable and unfavorable cardiovascular (side) effects. Short-acting beta-2 sympathomimetic drugs (SABA) and macrolides in particular can trigger arrhythmia and some SABAs are associated with a higher incidence of myocardial infarction. Detailed knowledge of the effects of drugs used for the treatment of lung and heart diseases on the respective other organ and the associated complications and long-term effects are essential in providing optimal medical care to the many patients who present with both respiratory and cardiovascular diseases. 相似文献

Leptin,sympathetic nervous system,and baroreflex function 总被引:3,自引:0,他引:3
Grassi G 《Current hypertension reports》2004,6(3):236-240
In addition to its direct effects on energy metabolism and caloric intake, leptin exerts several circulatory effects that
appear to be mediated by an interaction with the sympathetic nervous system and the major reflexogenic area involved in cardiovascular
homeostatic control—that is, the arterial baroreflex. In this paper, the relationships between the adipocyte hormone and the
neuroadrenergic function are reviewed, taking into account data collected in experimental animal models as well as in human
cardiovascular (hypertension and heart failure) and noncardiovascular (obesity) diseases that are characterized by a hyperadrenergic
state coupled with a hyperleptinemia. 相似文献

BACKGROUND: The magnitude of coronary mortality risk associated with diabetes or prior myocardial infarction (MI) is debatable. Modulating effects of age, risk factors, and duration of follow-up may explain discrepancies in previous research. Associations with noncardiovascular mortality are little explored. OBJECTIVES: To compare mortality patterns in men with a history of diabetes or MI and to assess modulating effects on mortality of age, cardiovascular risk factors, and follow-up duration. METHODS: We compared the 25-year mortality of 4809 men with diabetes only and 4625 men with MI only (all men aged 35-57 years). RESULTS: The adjusted hazard ratio (HR) for all-cause mortality for those with MI only vs those with diabetes only was 0.97 (95% confidence interval, 0.92-1.03; P =.32). The pattern of deaths was different: higher coronary mortality (HR = 1.37; P<.001) and lower mortality from noncardiovascular causes (HR = 0.66; P<.001) in those with MI only compared with those with diabetes only. This finding prevailed across all ages and levels of cardiovascular risk factors. Hazard ratios for coronary mortality significantly declined over follow-up (2.7, 1.7, 1.2, 1.1, and 1.0 for < or =5, 6-10, 11-15, 16-20, and >20 years of follow-up, respectively), whereas HRs for noncardiovascular mortality remained relatively constant. CONCLUSIONS: Overall, diabetes and MI were similarly strong predictors of total mortality. Higher mortality from noncardiovascular causes was observed in those with diabetes only, whereas prior MI was more strongly predictive of coronary mortality than diabetes at any age and level of cardiovascular risk factors. The difference in coronary mortality between the 2 groups was most evident in the first 10 years of follow-up. 相似文献

Although the benefits of antihypertensive drugs have been clearly established, they remain underused by vulnerable older populations. We examined whether the presence of noncardiovascular comorbidity deters use of antihypertensives in elderly with hypertension. We conducted a retrospective cohort study among 51,517 patients > or =65 years of age in the Pennsylvania Pharmaceutical Assistance Contract for the Elderly (PACE) Program during 1999 and 2000. All were hypertensive and had diagnoses and used treatments during 1999 to qualify for entry into 1 of the following 5 mutually exclusive cohorts: asthma/chronic obstructive pulmonary disease (COPD), depression, gastrointestinal (GI) disorders, osteoarthritis, or none of the 4 comorbidities. Proportions using antihypertensives in 2000 were assessed. Logistic regression analysis was used to identify the independent effects on antihypertensive use of the 4 comorbidities of interest, sociodemographic characteristics, other cardiovascular and noncardiovascular comorbidity, and health care utilization variables. After adjustments in multivariable analyses, antihypertensive use was consistently lower in patients with asthma/COPD (odds ratio [OR], 0.43; 95% confidence interval [CI], 0.40 to 0.47), depression (OR, 0.50; 95% CI, 0.45 to 0.55), GI disorders (OR, 0.59; 95% CI, 0.54 to 0.64), and osteoarthritis (OR, 0.63; 95% CI, 0.59 to 0.67) relative to those without these conditions. Reduced antihypertensive use was also associated with older age, female gender, white race, more severe other comorbidities, absence of some cardiovascular indications, hospitalizations, nursing home care, physician visits, and use of fewer other medications. Highly prevalent, noncardiovascular conditions appear to deter use of antihypertensives in elderly with hypertension. 相似文献

Systematization of pleiotropic actions of statins is presented with special stress on effects important for prevention of atherosclerotic diseases, nonatherosclerotic cardiovascular diseases, and diseases of noncardiovascular origin. Dependence of pleiotropic effects of statins on dose and duration of administration is shown. The review contains data on novel studies of pleiotropic effects favorably affecting endothelial function, oxidative stress, arterial pressure, angiogenesis, heart failure, and disturbances of cardiac rhythm. 相似文献

Sodium glucose cotransporter 2 (SGLT2) inhibitors are a class of drugs that were primarily developed for the treatment of type 2 diabetes mellitus. However, these agents have shown to provide additional beneficial effects. We will discuss three main topics regarding the use of SGLT2 inhibitors: noncardiovascular effects, cardiovascular benefits, and novel clinical indications. Multiple clinical trials and preliminary studies across varying disciplines have shown that these agents exhibit cardiorenal‐protective benefits, retinoprotective benefits, and may aid in weight loss without causing marked hypoglycemia. Therefore, these agents represent an avenue in clinical practice to manage comorbid conditions in the hyperglycemic patient. Because of their multifaceted effects and robust action, SGLT2 inhibitors represent therapy options for providers that not only provide beneficial clinical results but also reduce total patient drug burden. 相似文献

Predictive value of clinic and ambulatory heart rate for mortality in elderly subjects with systolic hypertension 总被引:9,自引:0,他引:9
Palatini P Thijs L Staessen JA Fagard RH Bulpitt CJ Clement DL de Leeuw PW Jaaskivi M Leonetti G Nachev C O'Brien ET Parati G Rodicio JL Roman E Sarti C Tuomilehto J;Systolic Hypertension in Europe 《Archives of internal medicine》2002,162(20):2313-2321
OBJECTIVE: To examine the association of clinic and ambulatory heart rate with total, cardiovascular, and noncardiovascular death in a cohort of elderly subjects with isolated systolic hypertension from the Systolic Hypertension in Europe Trial. METHODS: A total of 4682 patients participated, whose untreated blood pressure on conventional measurement at baseline was 160 to 219 mm Hg systolic and lower than 95 mm Hg diastolic. Clinic heart rate was the mean of 6 readings during 3 visits. Ambulatory heart rate was recorded with a portable intermittent technique in 807 subjects. RESULTS: Raised baseline clinic heart rate was positively associated with a worse prognosis for total, cardiovascular, and noncardiovascular mortality among the 2293 men and women taking placebo. Subjects with heart rates higher than 79 beats/min (bpm) (top quintile) had a 1.89 times greater risk of mortality than subjects with heart rate lower than or equal to 79 bpm (95% confidence interval, 1.33-2.68 bpm). In a Cox regression analysis, predictors of time to death were heart rate (P<.001), age (P<.001), serum creatinine level (P =.001), presence of diabetes (P =.002), previous cardiovascular disease (P =.01), triglyceride readings (P =.02), smoking (P =.04), and elevated systolic blood pressure (P =.05), while total cholesterol level was found to be nonsignificant in the model. In the ambulatory monitoring subgroup, clinic and ambulatory heart rates predicted noncardiovascular but not cardiovascular mortality. However, in a Cox regression analysis in which clinic and ambulatory heart rates were included, a significant association with noncardiovascular mortality was found only for clinic heart rate (P =.004). In the active treatment group, the weak predictive power of clinic heart rate for mortality disappeared after adjustment for confounders. CONCLUSIONS: In untreated older patients with isolated systolic hypertension, a clinic heart rate greater than 79 bpm was a significant predictor of all-cause, cardiovascular, and noncardiovascular mortality. Ambulatory heart rate did not add prognostic information to that provided by clinic heart rate. 相似文献
