In severe conditions, it may develop into more critical health problems like myocardial infarction, stroke or heart failure, which are some of the major reasons of death. [ 2 ] There are many causes contributing to blood vessel disorder including high blood cholesterol and calcium levels, blood clot formation and inflammation of arteries.
Other causes can include an obstructing clot in a hepatic vein (Budd Chiari syndrome) or compression from tumors or tuberculosis lesions. When the pressure increases in the portal vein, a collateral circulation develops, causing visible veins such as esophageal varices .
The National Heart, Lung, and Blood Institute promotes the DASH diet for controlling high blood pressure and maximizing your heart health. The DASH diet involves eating more: The DASH diet ...
Arterial stiffness may also affect the time at which pulse wave reflections return to the heart. As the pulse wave travels through the circulation it undergoes reflection at sites where the transmission properties of the arterial tree change (i.e. sites of impedance mismatch). These reflected waves propagate backward towards the heart.
A list of veins in the human body: Veins of the heart. Coronary sinus. Great cardiac vein; Oblique vein of left atrium; Middle cardiac vein; Small cardiac vein; Pulmonary veins; Superior vena cava. Brachiocephalic vein. Inferior thyroid vein; Inferior laryngeal vein; Pericardial veins; Pericardiophrenic veins; Bronchial veins; Vertebral vein ...
There is an increase in progesterone, which causes the veins to relax and potentially swell more easily. [6] There's also a significant increase in the blood volume during pregnancy, which tends to distend veins, causing valve dysfunction which leads to blood pooling in the veins.
The anatomy of the veins of the heart is very variable, but generally it is formed by the following veins: heart veins that go into the coronary sinus: the great cardiac vein, the middle cardiac vein, the small cardiac vein, the posterior vein of the left ventricle, and the oblique vein of Marshall. Heart veins that go directly to the right ...
The heart does not contain veins, but rather coronary sinuses that serve the purpose of returning de-oxygenated blood from the heart muscle. [ citation needed ] A thrombus is a type of embolism , a more general term for any material that partially or fully blocks a blood vessel.
