The purpose of this study is to determine the occurrence of scarring of the heart (cardiac fibrosis) and inflammation in those with perinatally acquired Human Immunodeficiency Virus (HIV) infection compared to people not infected with HIV. The information learned from this research may help the investigator to better understand the link between cardiac fibrosis and cardiac dysfunction and inflammation in those with perinatally acquired HIV infection compared to the uninfected. Participants will have a blood sample, complete a patient questionnaire, and have a Magnetic resonance imaging (MRI) and ultrasound of the heart. Researchers will review the medical record and past medical history, for information about your heart function and overall health. Research samples and data from this study will be stored indefinitely and used for other research. There are risks to participate in this study and those risks include side effects from the contrast agent used for the MRI scan, (such as headache and injection site pain), and risks from blood sampling.
This study will evaluate the efficacy and safety of metformin, in patients 18-65 years of age with homozygous plasminogen activator inhibitor-1 (PAI-1) deficiency, with or without cardiac fibrosis, for a period of 60 months. The starting dose of metformin will be 500 mg up to a maximum dose of 2000 mg for a period of 5 years with the aim to assess the safety and efficacy of metformin on prevention/stabilization or regression of cardiac fibrosis in a Treated population vs. a Comparison population.
Fibroproliferative diseases, including pulmonary, cardiac and vascular fibrosis share common pathogenetic mechanisms. Furthermore, cardiovascular comorbidities are frequently found in patients with IPF. However, the prevalence of cardiac and vascular fibrosis in patients with IPF have yet to be determined. Main Purpose of this study is to evaluate, with non-invasive methods (echocardiogram, endothelial function and pulse wave velocity) and blood biomarkers (galectins-3, osteopontin, periostin and pro-BNP), the presence of vascular fibrosis (vascular rigidity and endothelial function) and cardiac fibrosis (prevalence of HFpEF - Heart Failure with Preserved Ejection Fraction) in patients with idiopathic pulmonary fibrosis (IPF), compared to healthy controls.
The purpose of this study is to evaluate the relationship between insulin resistance (IR) and myocardial tissue abnormalities. The study will focus on a patient population, South Asians, with a high prevalence of IR.
This study evaluates whether circulating levels of aminoterminal propeptide of type III procollagen (PIIINP) can predict the cardiovascular events in hemodialysis patients.
The goals of this research will be to define some of the mechanisms underlying the progression and complications of heart failure (HF) with preserved left ventricular ejection fraction (HFPEF) Aim 1: to evaluate the differences in cardiac structure, function and fibrosis markers through the spectrum of HF stages in order to deepen the understanding of the pathophysiology driving HF progression. Aim 2: to define the mechanisms by which HF risk factors, such as hypertension, diabetes, obesity, and renal insufficiency, interact with age to increase HF risk, and to evaluate the role of precipitating factors such as myocardial ischemia, atrial fibrillation in HFPEF. Aim 3: to determine prognostic factors in HFPEF patients, by following these patients over time. Accordingly the investigators will correlate baseline data (echocardiographic, MRI or biomarkers) with incident cardiovascular events and determine whether these measures provide incremental prognostic information beyond clinical characteristics.
Muscular Dystrophy can affect the skeletal muscles and also the heart and breathing muscles, causing significant morbidity and mortality. As patients are now living longer, treatment of muscular dystrophies involves drugs that help improve heart function. However, better types of heart imaging studies are needed to understand how these treatments work. Researchers want to improve heart imaging to identify earlier indicators of heart dysfunction in muscular dystrophy patients and how these are changed by medical treatment. The new imaging indicators will also help identify candidates for entry into future clinical trials.
The purpose of this study is to determine whether Pycnogenol, a natural pine bark extract, is effective in modifying the age-dependent process of cardiac fibrosis and diastolic function in aged hypertensive subjects.
