Collapsed Artery In Heart
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
Depends: When blood flow is sufficiently reduced by a greater than 70% blockage of an artery or arteries, to the point of permanent damage or weaknening of the heart muscle, or when a plaque ruptures and a blood clot repeatedly forms with resulting blockage of blood flow, then an artery needs to be stented, or bypassed. ...Read more
See below: The Left anterior descending with its branches, diagonals and septal perforators, the left circumflex with its branches, obtuse marginals, and the right coronary artery with its branches, especially the posterior descending and posterolateral branches. ...Read more
Pectoris atherosclerosis congestive heart failure coronary artery disease dilate hypertension myocardial angina pectoris, what are these?
Cv words: These all refer to cardiovascular particulars. Pectoris = Chest. Atherosclerosis = vascular wall scarring from cholesterol deposit. Coronary artery disease = narrowing and atherosclerosis of heart arteries. Dilate = expand diameter. Hypertension = high blood pressure (within arterial network). Myocardial = heart. Angina pectoris = pain of chest from coronary artery disease, lack of oxygen to heart ...Read more
Cause: The symptoms will feel the same but the cause could be quite different. When the heart is not getting enough blood, it relaxes poorly after each heart beat. This can cause shortness of breath. In advanced stages, blocked heart arteries cause heart damage, pumping dysfunction, and heart failure. Valve disease can cause relaxation problems and heart damage as well despite normal circulation. ...Read moreSee 1 more doctor answer
Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?
Plumbing!: Blood must get to the body, else the fetus would not survive. The same is true once the baby is born. In utero, blood flows from pulm artery (pa) to aorta (ao) normally. Once born, the blood continues to flow this way so that blood can get to the body. When the PDA closes, the child becomes very sick. ...Read moreSee 3 more doctor answers
Any ideas why heart failures come from pulmonary embolism in the right upper lobe of the lung in arteriosclerosis?
Several ways: The pe can cause low oxygen including what goes to the heart. It can put strain on the heart, dilate the right side, cause hormones to be released cause tachycardia and due to that chf, arrhythmia and failure of the heart to push blood if big enough. It can then cause paradoxical pressures in the ventricles collapsing the left ventricle due to right pressure. ...Read more
