Atherosclerosis, especially when manifested as coronary artery disease (CAD), continues to be the number one cause of mortality and morbidity in developed nations and will soon become so in developing countries. Survivors of an acute heart attack have an increased risk of illness and death that is 1.5-15 times greater than in the general population. Sudden death occurs in myocardial infarction (MI) survivors at a rate 4-6 times greater than in the general population. After an initial recognized MI, 25% of male and 38% of female survivors die within 1 year. Within 6 years after a recognized MI, 18% of men and 35% of women will have a second MI, 7% of men and 6% of women will suffer sudden death, and 22% of men and 46% of women will be disabled with heart failure. Aggressive secondary prevention, therefore, is the key to containing and reversing the "malignant" natural history of CAD, since patients with CAD or CAD risk equivalents are already in the "high risk" category according to the Adult Treatment Panel III (ATP III) of the National Cholesterol Education rogram (NCEP). Treatment of dyslipidemia, especially the reduction of low-density lipoprotein (LDL) cholesterol levels to below 100 mg/dl, was recommended by the 2001 NCEP-ATP Guidelines. In 2004, based on the increasing evidence from several major clinical trials between 2001 and 2004, the NCEP-ATP reaffirmed its LDL goal of < 100 mg/dl in patients with CAD or coronary disease risk equivalents (including multiple risk factors), with an optional LDL goal of < 70 mg/dl in very-high-risk patients (including patients with established coronary heart disease plus other highrisk conditions) Findings from major studies, such as the Treating to New Targets (TNT) study, the Scandinavian Simvastatin Survival Study (4S), the Collaborative Atorvastatin Diabetes Study (CARDS), the Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial and, more recently, the Lipid-Lowering Arm of the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT-LAA), lend support to the idea that greater LDL cholesterol lowering than that achieved with standard doses of statins may be warranted in patients with CAD and metabolic syndrome, CAD and diabetes, CAD and congestive heart failure, and CAD and renal insufficiency. On the other hand, additional lipid reduction may also be warranted in patients with risk factors such as diabetes, hypertension or a history of stroke, but without manifest CAD and despite relatively normal cholesterol levels. These newer indications for statins, atorvastatin in particular, as part of more aggressive secondary and primary prevention, are reviewed in this paper.

The term "sarcopenia" describes the progressive decline of muscle mass, strength and function occurring with aging. It is not considered a disease, but the direct consequence of the aging process on the skeletal muscle. Multiple demographic (e.g. gender, race), biological (e.g. inflammatory status) and clinical (e.g. diabetes, metabolic syndrome, congestive heart failure, medications) factors are able to influence (positively or negatively) the skeletal muscle quality and quantity. The extreme paucity of clinical trials on sarcopenia in literature is mainly due to difficulties in designing studies able to isolate the aging process from its multiple and interconnected consequences. In the present review, we present the major factors to consider as potential sources of biased results when evaluating potential candidates for clinical trials on sarcopenia. The development of clinical trials exploring the nature of the sarcopenia process is urgent, but several controversial issues on this hallmark of aging still need clarification.

Heart Failure (CHF) is a very important public health problem in the world and certainly one of the most common debilitating diseases and cause of mortality. Current knowledge underlines that incidence rates are also influenced by the coexisting pathologic conditions that accelerate the development of disease or increase its severity. Important scientific evidence is emerging to demonstrate a strong correlation between HF and the metabolic syndrome (MetS). Hypolipemia-inducing medication offers the opportunity to discuss the possible existence of pharmacological substances that in addition to their specific targets have several demonstrated pleiotropic effects that could be beneficial in HF. Although several trials investigated statins treatment effects on HF in general, some evidence exists about the role that these drugs can have in the progression of the disease in the specific category of HF patients affected by MetS. In this review the possible positive effects of the statins treatment in this specific subset of patients are discussed.

The GOOD survey investigated the global cardiometabolic risk profile in adult patients with hypertension across 289 sites in four European regions (Northwest, Mediterranean, Atlantic European Mainland and Central Europe). Demographic, lifestyle, clinical and laboratory data were collected from eligible patients (n=3370) during a single clinic visit. In Central Europe, represented by Hungary, 44% of the participants had type II diabetes compared with 33% in the Atlantic European Mainland, and 26% in the Northwest and the Mediterranean regions. The prevalence of metabolic syndrome was also significantly higher in Central Europe (68%) and the Atlantic European Mainland (60%) than in the Northwest and the Mediterranean regions (50 and 52%, respectively). Fasting blood glucose, total cholesterol and triglyceride levels were all highest in Central Europe compared with the other three regions (P<0.001). In the Atlantic European Mainland, more patients had uncontrolled blood pressure (80%) compared with the other three regions (70-71%). Declared alcohol consumption was highest in the Atlantic European Mainland and exercise lowest in Central Europe. The prevalence of congestive heart failure, left ventricular hypertrophy, coronary artery disease and stable/unstable angina was higher in Central Europe compared with the other regions, whereas a family history of premature stroke or myocardial infarction, stroke, coronary revascularization and transient ischaemic attacks was all highest in the Atlantic European Mainland. These data indicate that many hypertensive patients across Europe have multiple cardiometabolic risk factors with the prevalence higher in Central Europe and the Atlantic European Mainland compared with Northwest and Mediterranean regions.

The metabolic syndrome, also known as the cardiometabolic syndrome (CMS), is a state of metabolic and vascular dysregulation that is associated with activation of the renin-angiotensin-aldosterone system (RAAS). Clinical components of the CMS include central or visceral obesity, hypertension (HTN), dyslipidemia, insulin resistance/hyperinsulinemia, and microalbuminuria that collectively convey increases in oxidative stress, inflammation, and subsequent endothelial dysfunction. The cardio-renal inflammation and oxidative stress enhanced in the CMS increases the risk for cardiovascular disease (CVD) and renal disease end-points such as stroke, congestive heart failure, and chronic kidney disease (CKD). The development of proteinuria is known to herald progressive kidney disease (e.g. CKD) and both are now well accepted as CVD risk factors. Evidence suggests a role for visceral obesity, insulin resistance/hyperinsulinemia, HTN, and other components of the CMS lead to an increased risk for proteinuria and progressive loss of renal function. Intervention with agents that block the RAAS (e.g. ACE inhibitors and Angiotensin type 1 receptor blockers) have been shown to reduce proteinuria, CKD progression, and CVD events. Herein, we will examine the relationship between RAAS intervention and reductions in CKD and CVD events.

Aldosterone is an adrenal hormone that regulates sodium, fluid, and potassium balance. Jerome Conn first described the syndrome of autonomous and excessive aldosterone secretion or "primary aldosteronism." Contrary to the historical belief, recent studies indicate that primary aldosteronism is a common cause of hypertension with a prevalence of 5-10% among general hypertensive patients. Various animal models have demonstrated that aldosterone in association with a high salt diet results in target-organ inflammation and fibrosis. Similarly, cross-sectional and observational human studies have demonstrated the association of aldosterone with development and severity of hypertension, congestive heart failure, coronary artery disease, chronic kidney disease, and metabolic syndrome. Several interventional studies have also demonstrated the beneficial effects of mineralocorticoid receptor antagonists in these disease processes, particularly hypertension, heart failure, and post myocardial infarction, further supporting the role of aldosterone in their pathogenesis. We review the role of aldosterone in these various cardiovascular disease processes along with potential mechanisms and treatment.

Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are thought to possess cardioprotective, cerebroprotective, and nephroprotective properties. Both classes of agents can prevent or reverse endothelial dysfunction and atherosclerosis, thereby potentially reducing the risk of cardiovascular events. Such a reduction has been shown with angiotensin-converting enzyme inhibitors in patients with coronary artery disease, but no such data are scarce with angiotensin receptor blockers (Valsartan in Acute Myocardial Infarction study). Both angiotensin-converting enzyme inhibitors and angiotensin receptor blockers have been shown to reduce damage in target organs, such as the heart and kidney, and to decrease cardiovascular mortality and morbidity in patients with congestive heart failure. These drugs (especially angiotensin receptor blockers) may successfully prevent atrial fibrillation and play a protective role in metabolic syndrome. In some clinical settings, combined therapy angiotensin-converting enzyme inhibitors with angiotensin receptor blocker (double blockade of the renin-angiotensin- aldosterone system) may appear the most effective.

Given the importance of adrenergic neural functioning in cardiovascular control, the hypothesis that an elevation in sympathetic drive represents a key pathophysiological feature of diseases characterized by an impairment in cardiac or renal function has been long considered. However, modern approaches to directly quantify sympathetic nerve firing in humans have only been possible in the last 2 decades to provide objective documentation for the hypothesis. This paper will review the evidence that conditions such as essential hypertension, congestive heart failure and metabolic syndrome are all accompanied by an increased sympathetic drive, which is likely in all of them to play a pathogenetic role. It will then offer examples showing that sympathetic influences are directly involved in the progression of organ damage associated with these conditions. Finally, evidence will be presented that a maximum degree of sympathetic activation can be seen in end-stage renal failure, in which a relationship between sympathetic activation and clinical outcome has been documented. This has therapeutic implications, which involve the need to use treatments that oppose rather than enhance sympathetic neural activation.

Adipose tissue is now accepted by the scientific and medical community to be a genuine endocrine organ, in addition to its classical role as an energy store. Adiponectin is one of the many adipocytokines that are secreted almost exclusively by adipose tissue. Alteration in blood adiponectin concentrations has been linked to many human diseases in numerous cross-sectional and prospective studies. In this review, we describe briefly the biological effects of adiponectin as revealed by basic scientific investigations. We also summarize the principles of blood adiponectin assays. Overall, lower blood adiponectin concentration is found in subjects with obesity, type 2 diabetes mellitus, dyslipidemia, and hypertension. These medical conditions are components of the metabolic syndrome and major risk factors for accelerated atherosclerosis. Plasma adiponectin levels are also expected to be lower in subjects with cardiovascular diseases, such as coronary artery disease, ischemic stroke and peripheral artery disease. Congestive heart failure (CHF) and cardiac arrhythmia are common end points in cardiovascular diseases. Surprisingly, higher blood adiponectin levels are frequently reported to predict mortality associated with CHF. Few human data regarding adiponectin and cardiac arrhythmia are available. Higher blood adiponectin level has been documented only in atrial fibrillation. We also summarize data on the role of the high molecular weight (HMW) isoforms of adiponectin and the effects of clinical treatment on the levels of total or HMW adiponectin. Whether adiponectin is a risk marker or a risk factor for the diseases reviewed in this article, and in many other human diseases, and their detailed pathogenic links awaits further investigation.

Residual coronary heart disease remains a significant problem even after adequate statin therapy for cardiovascular risk reduction as currently recommended by the Adult Treatment Panel III (ATP-III) of the National Cholesterol Education Program (NCEP). This is particularly true for the high risk patients as defined by ATP-III that includes those patients who have a greater than 20% 10-year risk of adverse cardiac events. For such patients the current goal of a low-density lipoprotein cholesterol (LDL-cholesterol) maintenance level of < or =100 mg/dL plasma appears to be suboptimal. Accumulating data from several recent randomized studies of more aggressive LDL-cholesterol reduction to levels below 70 mg/dL in the high risk patients favor acceptance of such a new lower target for LDL-cholesterol using more intensive statin therapy which would affect the treatment strategy for patients with coronary heart disease pre-percutaneous intervention, metabolic syndrome, diabetes mellitus, congestive heart failure, cerebrovascular disease and chronic kidney disease.
