Lipid-lowering nutraceuticals in clinical practice: position paper from an International Lipid Expert Panel.

Abstract: In recent years, there has been growing interest in the possible use of nutraceuticals to improve and optimize dyslipidemia control and therapy. Based on the data from available studies, nutraceuticals might help patients obtain theraputic lipid goals and reduce cardiovascular residual risk. Some nutraceuticals have essential lipid-lowering properties confirmed in studies; some might also have possible positive effects on nonlipid cardiovascular risk factors and have been shown to improve early markers of vascular health such as endothelial function and pulse wave velocity. However, the clinical evidence supporting the use of a single lipid-lowering nutraceutical or a combination of them is largely variable and, for many of the nutraceuticals, the evidence is very limited and, therefore, often debatable. The purpose of this position paper is to provide consensus-based recommendations for the optimal use of lipid-lowering nutraceuticals to manage dyslipidemia in patients who are still not on statin therapy, patients who are on statin or combination therapy but have not achieved lipid goals, and patients with statin intolerance. This statement is intended for physicians and other healthcare professionals engaged in the diagnosis and management of patients with lipid disorders, especially in the primary care setting.

Lipid lowering nutraceuticals in clinical practice: position paper from an International Lipid Expert Panel.

Abstract: 1.1. Cardiovascular disease and dyslipidemia: prevalence and global economic impact Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide, reaching 31% of deaths in 2012 [1]. In particular, atherosclerosis and ischemic heart disease (IHD) are the main causes of premature death in Europe and are responsible for 42% of deaths in women and 38% in men under 75 years old [2]. The global economic impact of CVD is estimated to have been US $906 billion in 2015 and is expected to rise by 22% by 2030 [3]. Cardiovascular diseases also represent the major cause of disability in developed countries. It has been estimated that their growing burden could lead to a global increase in loss of disability-adjusted life years (DALYs), from a loss of 85 million DALYs in 1990 to a loss of ~150 million DALYs in 2020, becoming a major non-psychological cause of lost productivity [4]. Several risk factors contribute to the etiology and development of CVD; they are divided into those modifiable through lifestyle changes or by taking a pharmacologic treatment (e.g. for hypertension, smoking, diabetes mellitus, hypercholesterolemia) and those that are not modifiable (age, male gender, and family history) [5]. Elevated total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) blood concentrations are the major modifiable risk factors for coronary heart disease (CHD), whereas high concentrations of plasma high-density lipoprotein cholesterol (HDL-C) in certain conditions are considered protective [6]. Moreover, LDL-C remains a fundamental CV risk factor (and a main target of therapy) even when statins are largely used in the general population [7]. An examination of the data of 18 053 participants aged ≥ 20 years who participated in the National Health and Nutrition Examination Surveys (NHANES) from 1999 to 2006 showed that the unadjusted prevalence of hypercholesterolemia ranged from 53.2% to 56.1% in United States adults [8]. Differences related to gender and race or ethnicity were observed; in particular, a lower rate of control was found among women than men and lower rates of having a cholesterol check and being told about hypercholesterolemia were reported by African Americans and Mexican Americans than whites [8]. A recent report from the American Heart Association confirmed that in the US only 75.7% of children and 46.6% of adults present targeted TC levels (TC < 170 mg/dl for children and < 200 mg/dl for adults, in untreated individuals) [9]. The pattern is similar in other Western countries [10, 11].

Quality of life questionnaire predicts poor exercise capacity only in HFpEF and not in HFrEF

Abstract: Background: The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is the most widely used measure of quality of life (QoL) in HF patients. This prospective study aimed to assess the relatio ...

Different determinants of exercise capacity in HFpEF compared to HFrEF.

Abstract: Quality of life is as important as survival in heart failure (HF) patients. Controversies exist with regards to echocardiographic determinants of exercise capacity in HF, particularly in patients with preserved ejection fraction (HFpEF). The aim of this study was to prospectively examine echocardiographic parameters that correlate and predict functional exercise capacity assessed by 6 min walk test (6-MWT) in patients with HFpEF. In 111 HF patients (mean age 63 ± 10 years, 47% female), an echo-Doppler study and a 6-MWT were performed in the same day. Patients were divided into two groups based on the 6-MWT distance (Group I: ≤ 300 m and Group II: >300 m). Group I were older (p = 0.008), had higher prevalence of diabetes (p = 0.027), higher baseline heart rate (p = 0.004), larger left atrium - LA (p = 0.001), longer LV filling time - FT (p = 0.019), shorter isovolumic relaxation time (p = 0.037), shorter pulmonary artery acceleration time - PA acceleration time (p = 0.006), lower left atrial lateral wall myocardial velocity (a’) (p = 0.018) and lower septal systolic myocardial velocity (s’) (p = 0.023), compared with Group II. Patients with HF and reduced EF (HFrEF) had lower hemoglobin (p = 0.007), higher baseline heart rate (p = 0.005), higher NT-ProBNP (p = 0.001), larger LA (p = 0.004), lower septal s’, e’, a’ waves, and septal mitral annular plane systolic excursion (MAPSE), shorter PA acceleration time (p < 0.001 for all), lower lateral MAPSE, higher E/A & E/e’, and shorter LVFT (p = 0.001 for all), lower lateral e’ (p = 0.009), s’ (p = 0.006), right ventricular e’ and LA emptying fraction (p = 0.012 for both), compared with HFpEF patients. In multivariate analysis, only LA diameter [2.676 (1.242–5.766), p = 0.012], and diabetes [0.274 (0.084–0.898), p = 0.033] independently predicted poor 6-MWT performance in the group as a whole. In HFrEF, age [1.073 (1.012–1.137), p = 0.018] and LA diameter [3.685 (1.348–10.071), p = 0.011], but in HFpEF, lateral s’ [0.295 (0.099–0.882), p = 0.029], and hemoglobin level [0.497 (0.248–0.998), p = 0.049] independently predicted poor 6-MWT performance. In HF patients determinants of exercise capacity differ according to severity of overall LV systolic function, with left atrial enlargement in HFrEF and longitudinal systolic shortening in HFpEF as the the main determinants.

Use of the “Minnesota Living with Heart Failure Questionnaire” Quality of Life Questionnaire in Kosovo’s Heart Failure Patients

Abstract: Background and aim: Quality of life (QoL) is one of the most important end-points in heart failure (HF) patients. The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is the most widely used measurement for assessing the QoL in HF patients. We used this questionnaire to evaluate the QoL in HF patients in Kosovo. Methods : The study subjects were 103 consecutive HF patients (63±10 years, 56 female) admitted in outpatient or in-patient clinics at University Clinical Centre of Kosovo. At the moment of evaluation the patients were clinically stable and on optimized drug therapy. Results: The overall median score of MLHFQ was 51 (mean 50±18). Female patients had higher total (p=0.015), emotional (p=0.022) and physical (p=0.019) MLWH compared to male patients. Te total MQLQ score had good correlation with 6MWT distance (p<0.001), but not with the level of NTproBNP level (p=0.364). Significant relationship was found also between MLWH and NYHA functional class in HF patients (p=0.002 for total, p=0.026 for emotional, and p<0.001 for physical MLHF score). NYHA functional class also significantly correlated with 6MWT distance (p<0.001 for both). Conclusions : The Albanian version of the MLHFQ proposed in this study proved to be valid for HF patients and served as a new and important instrument for assessing QoL in Kosovo’s patients. The MLHFQ was mildly higher in our patients compared with previous studies and was higher in female patients. The questionnaire score correlates with functional NYHA class, reflecting the severity of the disease, and with 6 minute walk test, reflecting exercise capacity.
