Association of Overweight With Increased Risk of Coronary Heart Disease Partly Independent of Blood Pressure and Cholesterol Levels A Meta-analysis o…

2007

Background: The extent to which moderate overweight (body mass index [BMI], 25.0-29.9 [calculated as weight in kilograms divided by height in meters squared]) and obesity (BMI, 30.0) are associated with increased risk of coronary heart disease (CHD) through adverse effects on blood pressure and cholesterol levels is unclear, as is the risk of CHD that remains after these mediating effects are considered. Methods: Relative risks (RRs) of CHD associated with moderate overweight and obesity with and without adjustment for blood pressure and cholesterol concentrations were calculated by the members of a collaboration of prospective cohort studies of healthy, mainly white persons and pooled by m…

Ketogenic diet, physical activity, and hypertension—a narrative review

2021

Several studies link cardiovascular diseases (CVD) with unhealthy lifestyles (unhealthy dietary habits, alcohol consumption, smoking, and low levels of physical activity). Therefore, the strong need for CVD prevention may be pursued through an improved control of CVD risk factors (impaired lipid and glycemic profiles, high blood pressure, and obesity), which is achievable through an overall intervention aimed to favor a healthy lifestyle. Focusing on diet, different recommendations emphasize the need to increase or avoid consumption of entire classes of food, with only partly known and only partly foreseeable consequences on the overall level of health. In recent years, the ketogenic diet (…

New diagnostic criteria of acute rheumatic fever: prevalence of silent carditis in a pediatric population

2017

Acute rheumatic fever and its sequel, chronic rheumatic heart disease, are important global health issues with an annual incidence of about 500.000 new cases and a prevalence of 34 million people worldwide affected by rheumatic heart disease. During the 20th century the incidence of ARF and the prevalence declined substantially in Europe, North America, and developed nations in other geographic locations. In Italy the incidence is about 4,1:100.000. Acute rheumatic fever is a systemic inflammatory response to group A streptococcal infection, which typically affects children and occurs two or three weeks after a throat infection. Although arthritis is the most common sign, carditis which com…

The clinical relevance of low-density-lipoproteins size modulation by statins.

2006

The predominance of small, dense low density lipoproteins (LDL) has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III; in fact, LDL size seems to be an important predictor of cardiovascular events and progression of coronary heart disease. Several studies have also shown that the therapeutical modulation of LDL size is of great benefit in reducing the risk of cardiovascular events. Hypolipidemic treatment is able to alter LDL subclass distribution and statins are currently the most widely used lipid-lowering agents. Statins are potent inhibitors of hydroxy-methyl-glutaryl-coenzyme A reductase, the rate-limiting en…

Low-density-lipoproteins size and cardiovascular prevention

2005

Low-density lipoprotein (LDL) size appears to be an important predictor of cardiovascular events and progression of coronary artery disease, and the predominance of small, dense LDL has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III. Yet, other authors have suggested that LDL subclass measurement does not add independent information to that conferred generically by LDL concentration and other standard risk factors. Therefore, the debate continues as to whether to measure LDL particle size for cardiovascular prevention and, if so, in which categories of patients. Since the therapeutic modulation of distinct LDL …

Subclinical impairment of lung function is related to mild cardiac dysfunction and manifest heart failure in the general population.

2016

Lung function impairment has previously been related to heart failure, although no overt cardiovascular or structural heart disease is present. The extent to which pulmonary function is related to subclinical left ventricular impairment in the general population remains to be investigated.15010 individuals from the general population (mean age 55±11years, 50.5% men) in the Gutenberg Health Study underwent spirometry, transthoracic echocardiography and biomarker measurement. Forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC) in percent of the predicted value and FEV1/FVC ratio were associated with echocardiographic measures of cardiac structure, systolic and diastolic func…

Effectively Predicting the Presence of Coronary Heart Disease Using Machine Learning Classifiers

2022

Coronary heart disease is one of the major causes of deaths around the globe. Predicating a heart disease is one of the most challenging tasks in the field of clinical data analysis. Machine learning (ML) is useful in diagnostic assistance in terms of decision making and prediction on the basis of the data produced by healthcare sector globally. We have also perceived ML techniques employed in the medical field of disease prediction. In this regard, numerous research studies have been shown on heart disease prediction using an ML classifier. In this paper, we used eleven ML classifiers to identify key features, which improved the predictability of heart disease. To introduce the prediction …

Cirugía de las arritmias en las cardiopatías congénitas

2008

La propia fisiopatología de las cardiopatías congénitas y el impacto de algunas correcciones quirúrgicas pueden predisponer al desarrollo de arritmias cardíacas, que incluyen taquicardia supraventricular macrorreentrante, flutter, fibrilación auricular, taquicardia auricular ectópica, taquicardia ventricular, síndrome del seno enfermo, bloqueo auriculoventricular y muerte súbita, entre otras. En la actualidad el tratamiento definitivo de estas arritmias y su profilaxis durante la corrección quirúrgica son procesos eficaces, con baja morbilidad y gran beneficio clínico para el paciente. En este trabajo se revisa el estado actual del tratamiento quirúrgico de las arritmias en las cardiopatías…

Exercise-Induced Sustained Ventricular Tachycardia without Structural Heart Disease: A Case Report

2020

Patient: Female, 51-year-old Final Diagnosis: Ventricular tachycardia Symptoms: Chest pain • shortness of breath Medication: — Clinical Procedure: Treadmill stress echocardiogram Specialty: Cardiology Objective: Unusual clinical course Background: Exercise-induced ventricular tachycardia (VT) has been widely reported in patients with preexisting structural heart disease or underlying ischemia and is attributed to reentry tachycardia and abnormal automaticity. However, studies regarding exercise-induced VT in individuals without evident structural heart disease are still limited. Case Report: A 51-year-old woman came to our practice for a treadmill stress echocardiogram. The patient experien…
