Silent myocardial ischemia (SMI) and silent coronary stenoses (CS) are two to seven times more frequent in diabetic patients than in non-diabetic patients. In addition to this, they have a higher predictive value for cardiovascular events than the classical cardiovascular risk factors, either taken alone or combined. Coronary arterial disease is the leading cause of mortality and morbidity in the diabetic population. Altogether, these data suggest that screening for SMI and silent CS is an important issue. We assume that detecting SMI and silent CS improves patient management, and leads to optimised follow-up, action taken on nutrition, exercise and lifestyle, management of the cardiovascular risk factors, and revascularisation procedures whenever possible. However, screening for SMI and silent CS is expensive and may induce morbidity. Selecting the patients with a high a priori risk of SMI and silent CS is therefore of major concern. Carotid or lower limb peripheral arterial disease, proteinuria, male gender, an age greater than 60 years, and two or more cardiovascular risk factors among smoking, microalbuminuria, dyslipidemia, hypertension, a family history of premature cardiac disease, and cardiac autonomic neuropathy have been demonstrated to be the best current predictors of SMI and silent CS. New markers, such as adhesion molecules, Lp(a), inflammation parameters or homocysteine, and endothelium function assessment might be of further help in the future.

Neurologists have little concern about the high atherosclerotic risk among epileptics. Recent evidences mount that chronic epilepsy and prolonged use of antiepileptic drugs (AEDs) are associated with multiple risk factors that are critically implicated in pathobiology and dysfunction of the vessel wall through complex molecular mechanisms that promote atherogenesis. This review is concerned with three metabolic alterations, which are attributed as major risk factors for atherosclerosis among epileptics: altered metabolism of a) homocysteine (Hcy), b) lipids and lipoproteins, and c) uric acid. Most conventional AEDs reduce folic acid levels, thereby raising Hcy levels. Hyperhomosysteinemia is recently believed to induce endothelial dysfunction and promote atherosclerosis through complex oxidative and excitatory neurotoxic molecular mechanisms. However, Hcy itself is a convulsing substance with increased seizure recurrence and intractability to antiepileptic medications. AEDs can disturb lipid metabolism with resultant hypercholestrolemia and dyslipidemia, common recognized risks for atherosclerosis. Altered uric acid metabolism is common among epileptics. Uric acid has been implicated in endothelial cell damage and decreased endothelial nitric oxide bioavailability. In the presence of atherosclerotic milieu, uric acid interacts with other substrate toxicities and increased reactive oxygen species, accelerating atherosclerosis. The above information forms the rationale for future routine screening and correction of such metabolic alterations in epileptics. A convincing argument now develops that routine polyvitamin supplementation (folic acid, vitamin B12, vitamin B6, vitamin C, vitamin E, and beta-carotene) becomes increasingly important for women and men receiving AEDs at all ages. The atheroprotective effect of multivitamins is through their antioxidant and anti-inflammatory effects together with their lipid and Hcy lowering effects.

Menopause-related oestrogen deficiency increases the risk of cardiovascular disease (CVD). The presence of abdominal obesity, dyslipidemia, hypertension, fasting hyperglycaemia or impaired glucose tolerance further aggravates the CVD risk imposed by menopause. A detailed personal history should be recorded, covering PCOS, gestational diabetes mellitus, alcohol intake and smoking, as well as a family history of cardiovascular disease. Screening of the a-symptomatic post-menopausal woman should include fasting lipid profile, plasma glucose and liver, renal and thyroid function tests. Serum low-density lipoprotein cholesterol (LDL-c)>130 mg/dL is associated with an increased risk of CVD. Levels of triglycerides (TG)>or=150 mg/dL and high-density lipoprotein cholesterol (HDL-c)<or=50 mg/dL coupled with an increase in small dense LDL and very low-density lipoprotein (VLDL) particles constitute the atherogenic dyslipidemia, which characterizes the metabolic syndrome. In women with previous VTE episodes, screening for thrombophilia is advisable, as well as an estimation of baseline homocysteine and C-reactive protein (CRP). Non-pharmacological intervention should be targeted towards smoking cessation, a low-salt, low-fat, high-fibre diet and increased physical activity.

The aim of this study was to study the effect of adding polyunsaturated fatty acid (PUFA) n-3 or placebo (containing oleic acid) to a combined statin-fibrate treatment on plasma lipoproteins, lipoperoxidation, glucose homeostasis, total homocysteine (tHcy) and microalbuminuria (MA) in patients with diabetic dyslipidemia (DDL). Twenty-four patients, who did not fulfill the recommended target lipid values with combined hypolipidemic therapy (pravastatin 20 mg+micronized fenofibrate 200 mg daily), were supplemented with 3.6 g PUFA n-3 daily for 3 months or placebo (olive oil) for the next 3 months. The concentrations of plasma lipids, fatty acid (FA) profiles of phosphatidylcholine (PC), cholesteryl esters (CE) and triglycerides (TG), tHcy levels, concentrations of conjugated dienes (CD) in low-density lipoprotein (LDL), and MA were determined in baseline state, after the PUFA n-3 and placebo treatment period. Supplementation with PUFA n-3 led to a significant decrease in plasma tHcy (-29%, P < .01) and TG (-28%, P < .05) levels, as well as to a significant decrease in MA (-24%, P < .05). The decrease in MA correlated significantly with the increase in total PUFA n-3 (r = -.509, P < or = .05) and docosahexaenoic acid (r = -.52, P < .01) in TG. The concentrations of CD in LDL increased significantly (+15%, P < .05). The supplementation with PUFA n-3 to the combined statin-fibrate treatment in patients with DDL decreased the TG and tHcy levels as well as MA. It could lead to decreased risk of atherothrombosis and delay of diabetic nephropathy onset and progression.

The clinical syndrome of chronic kidney disease (CKD) with coronary artery disease (CAD) is a clinical challenge. The risk of cardiovascular disease in patients with renal impairment appears to be far greater than in the general population. Despite the high prevalence of CKD related to cardiovascular disease (CVD), it remains understudied. Most of the current research comes from small community-based studies and retrospective reviews, assuming that patients with CKD will similarly benefit from treatments as patients with normal renal function. Most of the current clinical trials have excluded patients with CKD even though they represent a group of people at high risk for cardiovascular (CV) complications. CKD is associated with adverse CV outcomes and higher mortality even after adjustment for conventional risk factors. Declining renal function portends increasing CV risk and may be explained by several other factors that are being investigated, including inflammation, decreased vascular compliance, homocysteine, albuminuria and dyslipidemia. In addition, there is a lack of appropriate intervention in patients with CKD, despite established awareness of their high cardiovascular risk.

Patients submitted to orthotopic liver transplantation (OLT) show an increased rate of cardiovascular events. OLT subjects have high homocysteine (Hcy) levels, but no data are available on the association of Hcy with cardiovascular events. In a cross-sectional analysis, 230 subjects were studied at least 6 months after OLT (159 on cyclosporine, 71 on tacrolimus). Routine laboratory data and total Hcy were recorded, as well as the history of diabetes, hypertension, dyslipidemia, and overweight. Cardiovascular events occurring in a follow-up of 2-36 months were registered. OLT subjects had higher-than-normal Hcy (median 16.7 micromol/L, range 6.1-171.8) without difference between the 2 immunosuppressive agents. The prevalence of Hcy >15 micromol/L was also similar, and significantly correlated with creatinine levels. A total of 28 arterial events occurred in 25 patients during follow-up (11 in coronary arteries, 10 in peripheral arteries, and 7 in splanchnic arteries). Deep vein thromboses occurred in 2 patients, and splanchnic vein thromboses in 4 patients. Cardiovascular events were frequently associated to high Hcy and hypertension. Cox regression analysis showed that high Hcy was significantly associated with arterial events. The risk of any arterial event, coronary artery or peripheral artery event increased by nearly 10% for any increase in Hcy of 5 micromol/L. In conclusion, high Hcy may be involved in the pathogenesis of cardiovascular events in OLT patients. The usefulness of Hcy-lowering therapy remains to be verified.

Stroke represents a major health burden in our country. Ischaemic stroke has got several risk factors associated with increased chance of atherosclerosis. A small hospital-based study was done to look into the risk factors associated with ischaemic stroke. Forty patients with CT-confirmed cerebral infarction were taken for the study and detailed history and clinical findings were obtained. Investigations like complete haemogram, fasting blood glucose, urea, creatinine, lipid profile, serum Lp(a), homocysteine, fibrinogen, ECG, chest x-ray, echocardiography, MRI/MRA where indicated, were done to identify the risk factors as well. Results indicated that hypertension was the most prevalent (87.5%) risk factor followed by ischaemic heart disease (35%) and diabetes. Dyslipidaemia was also found in a significant number of cases, mostly elevated LDL, low HDL and elevated Lp(a). Fibrinogen and homocysteine were of less significance.

According to a k/DOQI work group, chronic kidney disease (CKD) can be present also in subjects with glomerular filtration rate (GFR) >90 mL/min or a serum creatinine (sCr) below 1.3 mg/dL. The aim of this study was to document the prevalence of clinical or biologic abnormalities among 190 cadaveric renal transplant patients with excellent and stable renal function at 6 months after transplantation as well as 5 years later. The recipients were 82 women and 108 men of mean age at transplantation of 44.56 +/- 11.73 years. All patients were on Neoral-based immunosuppression with at least 5-year follow-up. Mean sCr was 1.18 +/- 0.2 mg/dL. Mean GFR was 78.57 +/- 27.06 mL/min. Systolic blood pressure was >130 mm Hg in 56.6%, although 78.3% of patients were on antihypertensive therapy; 34.3% were anemic; 75.4% had serum cholesterol >200 mg/dL; 62.2% had serum triglyceride levels >170 mg/dL. Serum intact parathyroid hormone >100 pg/mL was observed in 38% of patients and 43% were on vitamin D supplementation, and 11.4% had developed posttransplant diabetes mellitus. With respect to controls, von Willebrand factor was higher in 81.2% (P < .0001; RR = 11); serum homocysteine levels in 75% (P < 0.001; RR = 7.61); PAI-1 in 37.5% (P = .0009; RR = 4). At 5 years posttransplantation we observed an overall improvement in these abnormalities. The vast majority of renal transplant patients with excellent graft function belong to stage 1 of CKD being affected by hypertension, dyslipidemia, anemia, and residual hyperparathyroidism. Markers of endothelial dysfunction were largely abnormal, a condition that could predispose to cardiovascular events.

Erectile dysfunction (ED) is associated with clinical atherosclerosis and several atherosclerotic risk factors including smoking, hypertension, dyslipidemia, diabetes mellitus, obesity and sedentary lifestyle. Clinical atherosclerosis is also associated with these same risk factors and with biomarkers of inflammation, thrombosis, endothelial cell activation. We evaluated the cross-sectional association between the degree of ED and levels of atherosclerotic biomarkers. A subcohort of 988 US male health professionals between the ages 46 and 81 years as part of an ongoing epidemiologic study had atherosclerotic biomarkers measured from blood collected in 1994-1995. These same men had in 2000, been retrospectively asked about erectile function in 1995 and in 2000. Biennial questionnaires since 1986 assessed medical conditions, medications, smoking, physical activity, body mass index, alcohol intake. The retrospective assessment of erectile function in 2000 for 1995 in these 988 men ranged from very good - 28.2%, good - 25.1%, fair - 19.2%, poor - 13.6%, to very poor - 13.9%. Men with poor to very poor erectile function compared to men with good and very good erectile function had 2.9 the odds of having elevated Factor VII levels (P=0.03), 1.9 times the odds of having elevated vascular cell adhesion molecule (P=0.13) and 2.0 times the odds of having elevated intracellular adhesion molecule (P=0.06) and 2.1 times the odds of having elevated total cholesterol/high-density lipoprotein ratio (P=0.02) comparing the top to bottom quintiles for each atherosclerotic biomarker after multivariate adjustment. Lipoprotein(a), homocysteine, interleukin-6 and tumor necrosis factor receptor, C-reactive protein and fibrinogen were not associated with the degree of erectile function after adjustment. We conclude that selected biomarkers for endothelial function, thrombosis and dyslipidemia but not inflammation are associated with the degree of ED in this cross-sectional analysis. Future studies evaluating the prospective association of ED, endothelial function and cardiovascular disease appear warranted.

Psoriasis is a chronic inflammatory skin disease that is associated with an increased cardiovascular risk profile. The systemic inflammation present in psoriasis, various systemic treatments for psoriasis and an increased prevalence of unhealthy life style factors may all contribute to this unfavorable risk profile. The purpose of this article is to provide an overview of what is known about these risk factors in psoriasis, the way they influence the cardiovascular risk of psoriasis patients, and what can be done to reduce this risk. Genetic studies demonstrate that psoriasis and cardiovascular disease share common pathogenic features in which, for example inflammatory cytokines like TNF-alpha and IL-1 play an important role. The chronic inflammation in psoriasis has an unfavorable effect on the cardiovascular risk profile. Multiple cardiovascular risk factors seem to be influenced; the blood pressure, oxidative stress, dyslipidemia, endothelial cell dysfunction, homocysteine levels and blood platelet adhesion. Moreover, classic cardiovascular risk factors like smoking and obesity that have an increased prevalence among patients with psoriasis, indirectly also worsen the cardiovascular risk profile by stimulating the psoriasis activity. Systemic treatments in psoriasis reduce the cardiovascular risk by diminishing the inflammation, but it should be taken into account that most therapies also have adverse cardiovascular effects like dyslipidemia, hyperhomocysteinemia and hypertension. As a consequence preventive measures may be indicated at least during long-term treatments. Prospective research is warranted to accurately estimate the increased cardiovascular risk in psoriasis, to determine the underlying processes and to consider preventive measures according to the absolute risk of cardiovascular disease. The present overview provides data to advice health care providers to pay more attention to the cardiovascular risk profile in psoriasis patients.
