Cardiac Damage Staging in Aortic Stenosis: A Perspective From the Cardiac Catheterization Laboratory
Salt-sensitive hypertension is common in the aged population. Increased fruit and vegetable intake reduces hypertension, but its effect on eventual diastolic dysfunction is unknown. This relationship is tested in the Dahl Salt-Sensitive (Dahl-SS) rat model of salt-sensitive hypertension and diastolic dysfunction. Table grape powder contains phytochemicals that are relevant to human diets. For 1...
BACKGROUND Anesthesiologists administer excess supplemental oxygen (hyper-oxygenation) to patients during surgery to avoid hypoxia. Hyper-oxygenation, however, may increase the generation of reactive oxygen species and cause oxidative damage. In cardiac surgery, increased oxidative damage has been associated with postoperative kidney and brain injury. We hypothesize that maintenance of normoxia...
To date, it remains unclear whether mild form of acute pancreatitis (AP) may cause myocardial damage which may be asymptomatic for a long time. Pathogenesis of AP-related cardiac injury may be attributed in part to ROS/RNS overproduction. The aim of the present study was to evaluate the oxidative stress changes in both the pancreas and the heart and to estimate the protective effects of 1-oxyl-...
INTRODUCTION AND OBJECTIVES To determine whether long-term prognosis is affected by myocardial damage taking place during percutaneous coronary intervention (PCI). METHODS The study included consecutive patients undergoing PCI. Those with elevated baseline cardiac marker levels were excluded. Cardiac markers were evaluated and an ECG was recorded before and 12 and 24 hours after PCI. Patients...
Objective(s):Higher cellular reactive oxygen species (ROS) levels is important in reducing cellular energy charge (EC) by increasing the levels of key metabolic protein, and nitrosative modifications, and have been shown to damage the cardiac tissue of diabetic mice. However, the relation between energy production and heart function is unclear. Materials and Methods:Streptozotocin (STZ, 150 mg...
BACKGROUND AND PURPOSE Stroke can lead to cerebrogenic cardiac arrhythmias. We sought to investigate the effect of ischemic stroke on cardiac function in a mouse model of permanent middle cerebral artery occlusion (pMCAO). METHODS Twenty-four hours after the induction of focal ischemia, cardiac function was measured in mice by endovascular catheterization of the heart. Immediately after hemod...
C ARDIAC INJURY commonly occurs in patients who sustain blunt thoracic trauma; the incidence in patients who survive transport to a hospital has been estimated at 10% to 20% depending on the diagnostic criteria used.‘-8 Most commonly, the injury is limited to myocardial contusion and the structural integrity of the heart remains intact.’ Although the signs and symptoms of significant cardiac st...
Aging is characterized by progressive decline in physiological and body function due to increase in oxidative damage. Gelam honey has been accounted to have high phenolic and nonphenolic content to attenuate oxidative damage. This study was to determine the effect of local gelam honey on oxidative damage of aged rats. Twenty-four male Spraque-Dawley rats were divided into young (2 months) and a...
Heart involvement in Cardiac Amyloidosis (CA) results a worsening of the prognosis almost all patients with both light-chain (AL) and transthyretin amyloidosis (ATTR). The mainstream CA is restrictive cardiomyopathy hypertrophic phenotype at cardiac imaging that clinically leads to heart failure preserved ejection fraction (HFpEF). An early diagnosis essential reduce damage improve prognosis. M...
