1/43. Ocular ischemic syndrome: two case reports of bilateral involvement.The ocular ischemic syndrome is characterised by ocular symptoms and signs secondary to severe carotid artery obstruction. In this paper, two cases of bilateral ocular involvement are presented. The first case was caused by severe bilateral carotid stenosis and the second by bilateral occlusion of the carotid artery.- - - - - - - - - - ranking = 1keywords = stenosis (Clic here for more details about this article) |
2/43. Usefulness of coronary MR angiography prior to angioplasty.The range of indications for percutaneous transluminal coronary angioplasty (PTCA) has increased greatly since the procedure was initially introduced. The success rate depends on the anatomy and length of the occlusion and on the state of the distal vessel. We present a case where the use of magnetic resonance angiography (MRA) allowed to evaluate the length of a subtotal occlusion prior to PTCA, and thus could have had an impact on therapeutic decisions. Coronary MR angiography is one of the many applications of breathhold MRI, where breathholding and segmented k-space acquisition are combined to provide anatomical images of coronary vessels. Coronary MR angiography allows reproducible visualization of coronary vessels. Even under adverse circumstances (poor cardiac triggering) the images are sometimes of sufficient quality to help make a diagnosis. This capability may increase the as yet limited clinical use of MR technology in the practice of cardiology.- - - - - - - - - - ranking = 1099.4739691032keywords = coronary (Clic here for more details about this article) |
3/43. Atherosclerotic narrowing of the left main coronary artery. A necropsy analysis of 152 patients with fatal coronary heart disease and varying degrees of left main narrowing.Histologic sections of the left main (LM) and the other three major coronary arteries were studied in 152 patients. The lumen of the LM in 35 patients was greater than 75% narrowed; in thirty, 50-75%; and in 87, less than 50% narrowed. The patients with greater than 75% narrowing were younger. angina pectoris and hyperlipoproteinemia, specifically type II, were more common (P less than 0.02) and acute transmural and healed subendocardial myocardial infarcts were less frequent (P less than 0.05) in the patients with greater 75% LM narrowing than in those with less than 50% narrowing. Of the three other major coronary arteries, the average number narrowed in the patients with greater than 75% LM narrowing was 2.9; in those with 50-75% LM narrowing 2.7, and in those with less than 50% LM narrowing, 2.4. Of the 35 patients with greater than 75% LM narrowing, 33 had greater than 75% luminal narrowing of each of the other three major coronary arteries. Narrowing of the LM, therefore, indicates severe narrowing of usually all major coronary arteries.- - - - - - - - - - ranking = 1884.8125184626keywords = coronary (Clic here for more details about this article) |
4/43. myocardial infarction associated with methadone and/or dihydrocodeine.chest pain and myocardial infarction occurring in young people with angiographically normal coronary arteries is well documented. Opiates have a cardioprotective effect and are used in acute heart attacks. We described a 22-year-old opioid addicted male patient who suffered a myocardial infarction following the consumption of methadone and dihydrocodeine.- - - - - - - - - - ranking = 157.06770987188keywords = coronary (Clic here for more details about this article) |
5/43. Eruptive xanthomas and chest pain in the absence of coronary artery disease.Because hyperlipidemia may present as xanthomas, a dermatologist may be the first to diagnose these skin lesions and associated lipid abnormalities. Xanthomas are of concern because of their association with coronary artery disease and pancreatitis. We describe the case of a 40-year-old white male with chest pain and eruptive xanthomas. Laboratory tests revealed severe hypercholesterolemia, hypertriglyceridemia, and diabetes mellitus, and the histopathology of the skin lesions was consistent with eruptive xanthomas. Surprisingly, even with overwhelming risk factors for both atherosclerosis and pancreatitis, this patient did not show evidence of either disease process. After initiating therapy for the diabetes and hyperlipidemia, the patient has had no recurrence of chest pain, and the skin lesions have gradually resolved. The most likely explanation for this patient's pattern of symptoms and laboratory results is the chylomicronemia syndrome, which can be seen in patients with type I or type V hyperlipoproteinemia.- - - - - - - - - - ranking = 785.33854935941keywords = coronary (Clic here for more details about this article) |
6/43. Multiple coronary artery aneurysms combined with abdominal aortic aneurysm.Coronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of a normal adjacent segment or the diameter of the patients's largest coronary vessel by as much as 1.5 times. It is an uncommon pathology with a frequency of 1-4% in routine autopsies or coronary angiographies. atherosclerosis plays an important role in the development of CAA, and it may be a predominant cause in the majority of patients. However, the timing of surgical intervention and the treatment options for CAA are still controversial. In this report, we present a patient who had multiple CAAs of all main coronary arteries and abdominal aortic aneurysm. Different treatment modalities and indications are also discussed.- - - - - - - - - - ranking = 1256.5416789751keywords = coronary (Clic here for more details about this article) |
7/43. Coronary heart disease in familiar hypercholesterolemia.autopsy findings of a 36-year-old male with familiar hypercholesterolemia were reported and discussed. Hyperlipoproteinemia found in this case might belong to the type IIa in the classification of hyperlipoproteinemia while there was no skin lesion such as xanthoma and hypertension. Remarkable strictures due to atherosclerotic plaques in the lumens of the right and left coronary arteries and wide-spread myocardial infarction in the left ventricle were found. In the aorta just above the aortic valve there were atherosclerotic plaques in which foam cells could be seen. From the histological findings of the aortic valve the possibility that the thickening of the valve might have been induced by a similar mechanism as that of aorta and coronary arteries was suggested.- - - - - - - - - - ranking = 314.13541974376keywords = coronary (Clic here for more details about this article) |
8/43. Fatal rhabdomyolysis caused by lipid-lowering therapy.Treatment of hypercholesterolemia has been shown to reduce mortality in patients with coronary artery disease. patients with severe lipid abnormalities may require high-dose statin therapy, at times used in combination with additional agents. We report a case of fatal rhabdomyolysis caused by the combination of simvastatin and gemfibrozil. Clinicians should be aware of risk factors for rhabdomyolysis, which include underlying renal insufficiency, high-dose statin therapy, and combination therapy with a fibrate.- - - - - - - - - - ranking = 157.06770987188keywords = coronary (Clic here for more details about this article) |
9/43. Four cases of tendinopathy in patients on statin therapy.During the last decade, statins have been widely prescribed as lipid-lowering drugs. Their overall safety profile is good. The main musculoskeletal side effects have consisted of muscle pain and weakness, peripheral neuropathy, and a few cases of drug-induced lupus. We report the first four cases of tendinopathy in patients receiving statin therapy. There were three men and one woman. The diagnoses were extensortenosynovitis at the hands (case 1), tenosynovitis of the tibialis anterior tendon (case 2), and Achilles tendinopathy (cases 3 and 4). Two patients were on simvastatin and two on atorvastatin. The tendinopathy developed 1 to 2 months after treatment initiation. The outcome was consistently favorable within 1 to 2 months after discontinuation of the drug. Similar cases have been reported to French pharmacovigilance centers. This report of four cases of tendinopathy draws attention to a possible and heretofore unrecognized side effect of a drug class that is becoming increasingly popular. Statins are effective in lowering high cholesterol levels in patients with type IIa or IIb hypercholesterolemia. They have been widely used for the last decade, particularly in the secondary and primary prevention of major coronary events. Statins act by inhibiting the enzyme hydroxy-3-methyl-glutaryl-coenzyme a (HMG-CoA) reductase. Although most patients tolerate statins extremely well, a few experience side effects requiring treatment discontinuation. Reported musculoskeletal side effects include myalgia and a few cases of rhabdomyolysis and polymyositis. Induced lupus and peripheral neuropathy are exceedingly rare.- - - - - - - - - - ranking = 157.06770987188keywords = coronary (Clic here for more details about this article) |
10/43. Prevention for the older woman. A practical guide to managing cardiovascular disease.American women are more likely to die from cardiovascular disease than from any other cause. Although hypertension is most prevalent, most deaths are attributed to coronary heart disease. heart disease in women manifests approximately 12 to 15 years later than in men, up until menopause. Then the severity of coronary artery lesions in women accelerates until it equals or surpasses that of men by the late 70s or early 80s. physicians can help older women reduce their risk for heart disease and stroke by managing hypertension and hypercholesterolemia and providing beta-blocker treatment when indicated after MI. Nonpharmacologic interventions may be effective as well. New guidelines for aspirin help identify women under age 80 who would benefit most from antiplatelet therapy.- - - - - - - - - - ranking = 314.13541974376keywords = coronary (Clic here for more details about this article) |
