Magnetic Resonance Imaging in the Diagnosis of Pulmonary Hypertension

Pulmonary HypertensionVentricular Function2 more

The aim of the present study is to identify changes in the cardiovascular system in patients with pulmonary hypertension (PH) by magnetic resonance imaging (MRI). MRI is accepted as golden standard method for the evaluation of left and right ventricular morphology and function. All patients who showed elevated pulmonary pressure in the right heart catheter investigation are assigned to MRI. Parameters derived from MRI are included in the clinical and therapeutic decisions. Well established as well as new MRI parameters are evaluated and compared to the results of right heart catheter. Further age-matched controls without known cardiac or pulmonary disease are investigated by native MRI.

Retrospective Treatment Pattern Survey for the Patients With Hypertension and Stroke

Hypertension

This study will address the treatment rate and control rate of hypertension, treatment pattern and factors that affect BP control by examining retrospective medical records of hypertension patients recovering from stroke, among outpatients coming to the Neurology Department in 10 university hospitals nationwide.

Recurrent Stroke Prevention Clinical Outcome Study

HypertensionStroke1 more

Objectives and Hypothesis Objectives: This study evaluates whether strict BP management is useful for the prevention of recurrent stroke. Hypertensive patients with history of stroke are treated with stepwise multi-drug therapy to achieve stricter BP target <120/80 mmHg in the strict BP control group and less stricter BP target <140/90 mmHg or <130/80 mmHg for patients with current DM/CKD/MI in the standard BP control group. The participants under the BP treatment achieving their respective BP target will be followed for recurrence of stroke. The study continues until the number of patients with the first recurrent stroke reaches a total of 330 between the two groups. The occurrence rates of recurrent stroke will be compared between the two groups. Hypotheses The incidence of recurrent stroke will be lower in a strict BP control group having lower BP target: <120/80 mmHg* than in a standard BP control group having BP target <140/90 mmHg or <130/80 mmHg for current DM/CKD/MI in patients with hypertension. Study design This will be a multicenter, randomized, open-label study. The study consists of a screening period, a titration period and a follow-up period. The screening period is a period between the date of consent and the enrollment date. Hypertensive patients with history of stroke are randomly assigned to either the strict BP control group having the target of <120/80 mmHg or the standard BP control group having the target of <140/90 mmHg without current DM, CKD or MI and <130/80 mmHg with current DM, CKD or MI. The titration period is the period finding a treatment which achieves target BP, and 24 weeks at maximum. Patients will be treated with stepwise multi-drug therapy using an angiotensin-receptor antagonist, diuretic, calcium channel blocker and aldosterone antagonist. The participants will be observed under the BP management for their respective BP target. The study will be continued until the number of patients with the first recurrent stroke reaches a total of 330 between two groups. The follow-up period will be 3 years. The recurrent rates of stroke in both groups will be compared from various aspects, and strict BP management will be investigated on the usefulness in prevention of recurrent stroke.

Relationship of Genes and Life Events to Blood Pressure

HypertensionPsychosocial Factors

Research suggests that blood pressure is influenced by both genetic and environmental factors. The goal of this study is to find genes that play a role in blood pressure and understand how they interact with life events (such as job stress) to influence blood pressure. We hypothesize that the gene for endothelin-1 is associated with increased blood pressure. Further, we predict that this genetic relationship is moderated by psychosocial stress factors, specifically job strain and marital cohesion.
