Erectile dysfunction (ED) is a highly prevalent and increasingly common, mainly vascular disorder. Most patients with chronic cardiovascular diseases experience decreased libido and frequency of sexual activity, as well as ED. Some unique organic and psychological factors contributing to ED have been identified in patients with underlying cardiovascular problems. Certain risk factors are common to the development of coronary artery disease, heart failure and ED, including diabetes mellitus, hypertension, smoking and dyslipidemia. Additionally, the use of medications such as beta blockers, digoxin and thiazide diuretics might eventually cause but more likely worsen sexual dysfunction. These unintended consequences can lead to medical noncompliance in misguided efforts to retain satisfactory sexual activity, and thereby worsen cardiovascular problems. Accordingly, it is important for physicians dealing with patients with cardiovascular diseases to address sexual concerns in their patients. After careful evaluation, most patients with stable cardiac disorders can resume sexual activity and/or can be treated for ED.

Considerable knowledge has accumulated in recent decades concerning the significance of physical activity in the treatment of a number of diseases, including diseases that do not primarily manifest as disorders of the locomotive apparatus. In this review we present the evidence for prescribing exercise therapy in the treatment of metabolic syndrome-related disorders (insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity), heart and pulmonary diseases (chronic obstructive pulmonary disease, coronary heart disease, chronic heart failure, intermittent claudication), muscle, bone and joint diseases (osteoarthritis, rheumatoid arthritis, osteoporosis, fibromyalgia, chronic fatigue syndrome) and cancer, depression, asthma and type 1 diabetes. For each disease, we review the effect of exercise therapy on disease pathogenesis, on symptoms specific to the diagnosis, on physical fitness or strength and on quality of life. The possible mechanisms of action are briefly examined and the principles for prescribing exercise therapy are discussed, focusing on the type and amount of exercise and possible contraindications.

Cardiovascular disease has been the leading cause of morbidity and mortality in American women; yet, until recently, there was no mandate to specifically include women in clinical trials of the major cardiovascular drugs. Despite new regulations, there is still a lack of readily available data for the clinician to use when planning drug therapy for women, as many of the drugs in use today were developed and tested prior to the new regulations being in effect. The purpose of this article is to provide advanced practice nurses with the most current information on the use of cardiovascular drugs in women. Information on the unique biological features of women is first presented to provide background material for subsequent sections. This is followed by an explanation of pharmacokinetic processes in women to include information on absorption, distribution, and clearance of drugs. A brief review of the effects of the phases of the menstrual cycle on drug therapy is given and then issues related to the profound physiologic changes in pregnancy and subsequent effects on drug therapy are reviewed. An analysis of the strength of the available evidence on drug therapies in women from the major trials on acute coronary syndromes, heart failure, dyslipidemia, atrial fibrillation, and hypertension is provided. Finally, implications for practice, including recommendations for drug prescription, are summarized.

Patients with type 2 diabetes mellitus are at high risk for cardiovascular events and heart failure. The major serious complication of this disorder is large vessel atherosclerosis leading to myocardial infarction and stroke. Aggressive target setting for modifiable cardiovascular risk factors such as dyslipidemia, hypertension, and a procoagulant state, and judicious choice of efficacious therapies have been shown to produce significant reductions in cardiovascular events. The effectiveness of percutaneous coronary intervention (PCI) in diabetes is discussed, and the factors that may influence outcomes are explored. A major unresolved question is the potential role of tight glucose control for reducing macrovascular complications in patients with diabetes. With the increased attention being given to cardiovascular risk factor reduction, the opportunity exists to substantially decrease the largest causes of mortality in diabetic patients. This article reviews the current and emerging therapeutic strategies for these purposes from the cardiologists' point of view.

Consumption of trans fatty acids (TFA) predicts higher risk of coronary heart disease, sudden death, and possibly diabetes mellitus. These associations are greater than would be predicted by effects of TFA on serum lipoproteins alone. Systemic inflammation and endothelial dysfunction may be involved in the pathogenesis of atherosclerosis, acute coronary syndromes, sudden death, insulin resistance, dyslipidemia, and heart failure. Evidence from both observational and experimental studies indicates that TFA are pro-inflammatory. Limited evidence suggests that pro-inflammatory effects may be stronger for trans isomers of linoleic acid (trans-C18:2) and oleic acid (trans-C18:1), rather than of palmitoleic acid (trans-C16:1), but further study of potential isomer-specific effects is needed. TFA also appear to induce endothelial dysfunction. The mechanisms underlying these effects are not well-established, but may involve TFA incorporation into endothelial cell, monocyte/macrophage, or adipocyte cell membranes (affecting membrane signaling pathway relating to inflammation) or ligand-dependent effects on peroxisome proliferator-activated receptor (PPAR) or retinoid X receptor (RXR) pathways. Activation of inflammatory responses and endothelial dysfunction may represent important mediating pathways between TFA consumption and risk of coronary heart disease, sudden death, and diabetes. Further study is indicated to define these effects of TFA and the implications of such effects for cardiovascular health.

Diabetes mellitus (DM) is considered a major public health problem in both developed and developing countries due to its chronic complications, at the macro or microcirculation, with great impact on mortality and morbidity in all patients. The disease is considered the end of a pathophysiologic process involving peripheral and hepatic insulin resistance and reduced insulin secretion that have been started years before the clinical diagnosis. Metabolic syndrome (MS) is a disorder that results from the increasing prevalence of obesity worldwide. DM is frequently associated with clinical and laboratory features of MS, like abdominal obesity, hypertension, dyslipidemia and microalbuminuria that are also risk factors for cardiovascular disease. Populational studies have demonstrated increasing prevalence of all the features of MS from pre-diabetes to clinical DM resulting in a great risk of cardiovascular disease. The prevalence of MS in DM type 2 is estimated to be >80%. Glitazones are PPAR-gamma agonists that improve insulin sensitivity. These drugs induce the transcription of genes related to glucose and lipid metabolism, and expression of inflammatory and endothelial proteins associated with atherosclerosis process resulting in an improvement in endothelial function. However several questions need to be clarified regarding the glitazones, in special those associated with their adverse effects such as weight gain, edema and heart failure.

Acquired toxoplasmosis is a widespread parasitic disease caused by an obligate intracellular protozoan, Toxoplasma gondii. Humans are infected by consuming undercooked or raw meat containing tissue cysts or by ingesting oocysts in food or water contaminated with feline faeces. Most cases of Toxoplasma gondii infections in immunocompetent individuals are asymptomatic. Although acquired toxoplasmosis is usually a mild infection, it may be life-threatening in immunocompromised patients. In this report we present a 67-year-old HIV-negative woman with acute toxoplasmic perimyocarditis, heart failure and with a history of ischemic heart disease, hypertension and dyslipidemia. The diagnosis was based on clinical characteristics, echocardiographic examinations, elevated inflammatory markers and the presence of IgM and IgG antibodies against Toxoplasma gondii. We conclude that Toxoplasma gondii infection should be considered in each case of perimyocarditis with concomitant, significant diagnostic and therapeutic problems, especially in immunocompromised patients. This paper also reviews differential diagnosis of elevated CA 125 serum levels in postmenopausal women.

Endothelium has many important functions including the control of blood-tissue permeability and vascular tonus, regulation of vascular surface properties for homeostasis and inflammation. Nitric oxide is the chief molecule in regulation of endothelial functions. Nitric oxide deficiency, which is also known as endothelial dysfunction, is the first step for the occurrence of many disease states in cardiovascular system including heart failure, hypertension, dyslipidemia, insulin resistance, diabetes mellitus, hyperhomocysteinemia and smoking. This review deals with the importance of nitric oxide for cardiovascular system. It also includes the latest improvements in the diagnosis and treatment of endothelial dysfunction.

Statins are effective in the prevention of coronary heart disease (CHD), a leading cause of heart failure (HF). Secondary analyses from 11 randomized clinical trials of patients with high-risk acute or stable coronary heart disease, but without HF, suggest that statins may prevent new-onset HF or HF-related hospitalization. In persons with established HF, several cohort studies found an approximate 35% relative risk reduction in all-cause mortality. While ongoing randomized clinical trials will help to determine the efficacy of statins in persons with established HF, it is reasonable to consider this class of medications in patients with a history of cardiovascular disease, dyslipidemia or diabetes mellitus, and who have either developed, or who remain at risk of, HF.

Cardiovascular disease has been well documented in patients with Human Immunodeficiency Virus infection, especially after the introduction of highly active antiretroviral therapy. At present, HIV infection is one of the leading causes of acquired cardiovascular disease including heart failure. Some of the changes observed in these patients include left ventricular systolic dysfunction, dilated cardiomyopathy, congestive heart failure, myocarditis, lipodystrophy, dyslipidemia, insulin resistance, accelerated atherosclerosis including myocardial infarction, prothrombotic state, pericardial effusion, pulmonary hypertension, autonomic dysfunction, and malignancy. This article summarizes the main findings in the principal HIV-associated cardiovascular manifestations in order to stimulate its early recognition so helping in early intervention and therapy.
