Filter by:Postoperative Cognitive Dysfunction(POCD) is commonly seen in cardiac surgery, which may lead to poor pognosis. Cerebral small vessel disease(CVSD) is refer as the main resource of delirium among elderly people. In the study, CVSD will be diagnosed using multimodal MRI. And we want to select a high correlating COPD biomarker through CyTOF. We also want to investigate a medical model to select the high risk patients who may suffer from POCD after cardiac surgery.
This is a randomized, double-blinded, placebo-controlled, multi-center trial. Cerebral small vessel disease (CSVD) patients will be diagnosed according to STRIVE standards and randomized into the Pentoxifylline sustained-release tablet group and placebo group. The purpose of this trial is to assess the efficacy of Pentoxifylline sustained- release tablets on CSVD.
The primary objectives of this trial are: 1. Efficacy evaluation of amlodipine folic acid tablets: To assess the effects of amlodipine folic acid tablets 5.8 mg (5 mg amlodipine + 0.8 mg folic acid)versus amlodipine tablets 5 mg in preventing all-cause stroke in cerebral small vascular disease (CSVD) patients with hypertension and elevated homocysteine (Hcy) level. 2. Intensive Antihypertensive Therapy: To assess the effect of intensive antihypertensive therapy (SBP<130 mmHg) versus standard antihypertensive therapy (SBP 130-<140 mmHg) in reducing risk of combined cardio-cerebrovascular events in CSVD patients with hypertension and elevated Hcy level, using two basic anti-hypertensive drugs, amlodipine tablets 5 mg or amlodipine folic acid tablets 5.8 mg.
The aim of the study is to: - detect changes in retinal structure and microvasculature in patients with cerebral small vessel disease using optical coherence tomography angiography , correlate these changes with brain imaging markers and determine if ( OCTA ) can be used as a screening tool for cerebral small vessel disease.
Hypertension is known to be the major risk factor for stroke. The most common cause of secondary hypertension, primary aldosteronism (PA), is characterized by the excessive secretion of aldosterone and is related to hypertension and hypokalemia. PA accounts for 3-10 % of hypertensive patients, and a higher incidence of vascular complications compared to patients with essential hypertension was observed in several studies. The vascular injury from excessive aldosterone can occur via oxidative stress and collagen remodeling, causing endothelial dysfunction and fibrosis in the vasculature. The association between cerebral small vessel disease (cSVD) and hypertension has been well studies in the past decades. However, not much study has focused on the cSVD burden in patient with PA. The goal of this study is to understand the features of cSVD in patients with PA and for the purpose of understanding the underlying pathophysiology of cerebrovascular injury in this particular patient group.
