Ischemic heart disease is caused by an imbalance between the myocardial blood flow and the metabolic demand of the myocardium. Reduction in coronary blood flow is related to progressive atherosclerosis with increasing occlusion of coronary arteries. Blood flow can be further decreased by superimposed events such as vasospasm, thrombosis, or circulatory changes leading to hypoperfusion.
Coronary artery perfusion depends upon the pressure differential between the ostia (aortic diastolic pressure) and coronary sinus (right atrial pressure). Coronary blood flow is reduced during systole because of Venturi effects at the coronary orifices and compression of intramuscular arteries during ventricular contraction.
Factors reducing coronary blood flow include:
Decreased aortic diastolic pressure
Increased intraventricular pressure and myocardial contraction
Coronary artery stenosis, which can be further subdivided into the following etiologies:
Fixed coronary stenosis
Acute plaque change (rupture, hemorrhage)
Coronary artery thrombosis
Vasoconstriction
Aortic valve stenosis and regurgitation
Increased right atrial pressure
40 micron collateral vessels are present in all hearts with pressure gradients permitting flow, despite occlusion of major vessels. In general, the cross-sectional area of the coronary artery lumen must be reduced by more than 75% to significantly affect perfusion. Coronary atherosclerosis is diffuse (involving more than one major arterial branch) but is often segmental, and typically involves the proximal 2 cm of arteries (epicardial).
"Thrombolytic therapy" with agents such as streptokinase or tissue plasminogen activator (TPA) is often used to try and lyse a recently formed thrombus. Such therapy with lysis of the thrombus can re-establish blood flow in a majority of cases. This helps to prevent significant myocardial injury, if early (less than an hour or so) in the course of events, and can at least help to reduce further damage.
Kidney Stones, acute as well as chronic, can be effectively treated with Homeopathic Medicines. Homeopathic treatment can avoid surgery in many cases. It is highly recommended in cases where tendency of having recurrent stones is there. Patient’s case history is studied in detail and a well selected homeopathic medicine is given which removes this tendency from patient’s body so that he does not have any more stones again. It has especially proved very helpful in cases of stones where surgery or other procedure is not advisable due to various reasons. All homeopathic medicines are safe, natural, easy to administer and without any adverse effects. If you have any specific question about your condition.
Causes of Kidney Stones
Infection or obstruction may play a part in kidney stone formation. Sometimes they occur when the level of blood calcium is abnormally high. Occasionally, stones may develop when the blood level of uric acid is too high, usually from over consumption of meat. Excessive dietary intake of calcium and oxalate and low fluid intake have also been associated with formation of stones. In most cases, however the cause is not known. It has been found that certain persons are having a tendency of forming recurrent urinary stones. Even after treating successfully once, they tend to form stones again and agai
Signs of Kidney Stones
The most common complaint arising from kidney stone (Renal Calculus; Plural - Calculi) is intermittent dull pain in the loin or back, increased by movement. Sometimes this pain is very severe. Following may be the other complaints:
-
Extreme pain in back or side
-
Blood in urine
-
Fever and chills
-
Vomiting
-
A burning feeling when you urinate
Kidney stones are made up of salt and other minerals. They usually pass through in the urine on a regular basis. Most kidney stones go through the urinary tract unnoticed because they are normally quite small. Sometimes, however, they can get large enough to be noticed. This is often extremely painful as the larger kidney stones pass through the ureter, bladder and urethra. Kidney stones can also get stuck along the way, causing infections, increased pain and sometimes damage to the kidneys. Kidney stones can be broken up to prevent pain, infection and kidney damage.
In some people, chemicals crystallize in the urine and form the beginning, or nidus, of a kidney stone. These stones are very tiny when they form, smaller than a grain of sand, but gradually can grow over time to a 1/10 of an inch or larger. Urolithiasis is the term that refers to the presence of stones in the urinary tract, while nephrolithiasis refers to kidney stones. The size of the stone doesn't matter as much as where it is located.
When the stone sits in the kidney, it rarely causes problems, but when it falls into the ureter, it acts like a dam. As the kidney continues to function and make urine, pressure builds up behind the stone and causes the kidney to swell. This pressure is what causes the pain of a kidney stone, but it also helps push the stone along the course of the ureter. When the stone enters the bladder, the obstruction in the ureter is relieved and the symptoms of a kidney stone are resolved.
Endometriosis is a condition in which the lining of the uterus gets displaced and appears in various sites in the body, including the ovaries, the bladder, or the bowel. Although the cause of this condition is unknown, it is sustained by ovarian hormones. Endometriosis can lead to varying symptoms, including heavy, painful periods, breast swelling, backache before periods, infertility, painful intercourse, dizziness, and depression. Conventional treatments for it are diverse and problematic. The conventional pharmacological treatment is with drugs that inhibit ovarian or pituitary hormones. These drugs produce various masculinizing effects, including increased body hair and irreversible changes in the voice. Some physicians recommend surgical treatment in which the displaced cells are burned out with a laser, or removal of the uterus, Fallopian tubes, and/or ovaries. Because some women experience great pain with this condition, they are desperate for any relief. These conventional medical treatments sometimes provide relief, but at the cost of new problematic symptoms and sometimes at the cost of the recurrence of the original condition. Michael Carlston, MD, a Homeopath and assistant clinical professor at the University of California at San Francisco School of Medicine, asserts that Homeopathic medicines can be very helpful at the early and middle stages of endometriosis, though because of severe scarring during advanced stages of the disease, they are not very effective later on. Endometriosis is not an ailment amenable to self-care; professional Homeopathic care is required.
