Thiamine Overdose. Overdosing on thiamine, or vitamin B-1, is rare but can cause severe symptoms. Mild symptoms of an overdose include weakness and a headache, the American Pregnancy Association reports. In some cases, high vitamin B-1 levels can cause a rapid, irregular heart beat and low blood pressure.
Ascending Aorta - initial part of the aorta that begins from the aortic valve and extends from the left ventricle of the heart to the aortic arch. Coronary Arteries - arteries branching from the ascending aorta to supply oxygenated blood to the heart wall.
The aorta is the largest blood vessel in the body. It carries freshly oxygenated blood out of the heart so that it can be distributed to the circulatory system. In most people, the aorta follows a relatively straight path, but in people with tortuous aorta, the vessel may be twisted or distorted.EarlyForest -- Sometimes tortuous aortas can indirectly cause abdominal aortic aneurysms, like pharmchick78 was talking about. Since a tortuous aorta is abnormal, sometimes the wall of the aorta can be weaker, leading to an aortic aneurysm, or, worst case scenario, an aortic aneurysm rupture.
