Abstract
We sought to determine the prevalence and correlates of valvular heart diseases (VHD) in the elderly population. The participants' personal information, medical history, behavioral habits and clinical status were assessed by questionnaire, while the left ventricular dimensions, function and the presence and severity of VHD were evaluated by transthoracic echocardiography. This study analyzed the data of 3948 participants who were older than 60 years. Significant VHD was present in 1.93% of participants; the standardized prevalence of VHD among the elderly population in Hubei was 2.05% (95% CI: 1.61-2.49). The most frequent VHD was aortic regurgitation, followed by tricuspid regurgitation, mitral regurgitation and multiple valve diseases. Univariate analysis results indicated that compared with participants without VHD, those with VHD were older (p < 0.001), with a higher body mass index (BMI) (p < 0.001), were more likely to smoke (p = 0.04), and had higher rates of coronary artery disease (CAD) (p < 0.001) and arrhythmia (p < 0.001). The results of multinomial regression analysis of complex sampling indicated that combined mitral and aortic valve diseases were related to older age, male sex and smoking; CAD was associated with single left-sided VHD.

Abstract
OBJECTIVES The aim of the present study was to retrospectively evaluate the prevalence of concurrent coronary artery disease in patients who underwent surgery due to severe valvular heart disease. The study also investigated the association of coronary artery disease with the type of valvular heart disease. MATERIALS AND METHODS A total of 241 patients (123 females [51%]), who had underwent single valvular heart surgery, were included in the study. The patients who underwent valve replacement surgery were divided into four groups: patients with severe mitral stenosis (MS), patients with severe mitral regurgitation (MR), patients with severe aortic regurgitation (AR), and patients with severe aortic stenosis (AS). Age, DM, HT, history of smoking, and LDL values were recorded as the risk factors for CAD. RESULTS Coronary artery disease was detected in 26.4% of patients with mitral stenosis and 57.7% of patients with aortic stenosis. Of the patients with mitral insufficiency, 41.9% had CAD, and 44.4% of the patients with aortic insufficiency had CAD. CONCLUSION The comparison of MS and AS groups revealed significantly higher prevalence of CAD in the AS group. There was no statistically significant difference between the MR and AR groups in terms of the prevalence of CAD. The comparison of MS and MR groups revealed significantly higher prevalence of CAD in the MR group. Furthermore, the comparison of these groups in terms of the extensiveness of the coronary artery disease revealed significantly higher Gensini score in the MR group.

Abstract
To evaluate the usefulness of preoperatie coronary angiography in patients undergoing preoperative investigation because of valvular heart disease, we performed coronary angiography in a consecutive series of 329 patients. The prevalence of significant coronary artery disease was 32%. Asymptomatic coronary artery disease was present in 13%. Angina pectoris proved to be a poor predictor of coronary artery disease in aortic valve disease. In mitral valve disease, however, the specificity was high. A cost-benefit calculation was carried out in order to assess what advantage routine coronary angiography might have. According to this, coronary angiography should be performed in all patients suffering from valvular heart disease with angina pectoris, whereas it can be omitted in younger patients without angina. A cut-off point of 60 years seems appropriate for aortic valve disease and 65 years for mitral valve disease.

Abstract
15-lipoxygenase (15-LO) has been implicated in the inflammation of chronic bronchitis (CB), but it is unclear which of its isoforms, 15-LOa or 15-LOb, is primarily involved. To detect 15-LO gene (mRNA) and protein expression, we have applied in situ hybridization (ISH) and immunohistochemistry (IHC), respectively, to bronchial biopsies obtained from 7 healthy nonsmokers (HNS), 5 healthy smokers (HS), and 8 smokers with CB, and additionally include the airways of lungs resected from 11 asymptomatic smokers (AS) and 11 smokers with CB. Compared with HNS, biopsies in CB demonstrated increased numbers of 15-LOa mRNA+ cells (median: HNS = 31.3/mm(2) versus CB = 84.9/mm(2), P < 0.01) and protein+ cells (HNS = 2.9/mm(2) versus CB = 32.1/mm(2), P < 0.01). The HS group also showed a significant increase in protein+ cells (HNS = 2.9/mm(2) versus HS = 14/mm(2), P < 0.05). In the resected airways, 15-LOa protein+ cells in the submucosal glands of the CB group were more numerous than in the AS group (AS = 33/mm(2) versus CB = 208/mm(2); P < 0.001). 15-LOa mRNA+ and protein+ cells consistently outnumbered 15-LOb by approximately 7- and 5-fold, respectively (P < 0.01). Quantitative reverse transcriptase polymerase chain reaction of complementary biopsies confirmed the increased levels of 15-LOa in CB compared with that in either HNS or HS (P < 0.05). There was no difference between the subject groups with respect to 15-LOb expression. The numbers of cells expressing mRNA for 15-LOa in CB showed a positive association with those expressing interleukin (IL)-4 mRNA (r = 0.80; P < 0.01). We conclude that the upregulation of 15-LO activity in the airways of HS and of smokers with CB primarily involves the 15-LOa isoform: the functional consequences of its association the upregulation of IL-4 in chronic bronchitis requires further study.

Abstract
OBJECTIVES We sought to develop and validate a model that estimates the risk of obstructive coronary artery disease in patients undergoing operations for mitral valve degeneration and to demonstrate its potential clinical utility. METHODS A total of 722 patients (67% men; age, 61 +/- 12 years) without a history of myocardial infarction, ischemic electrocardiographic changes, or angina who underwent routine coronary angiography before mitral valve prolapse operations between 1989 and 1996 were analyzed. A bootstrap-validated logistic regression model on the basis of clinical risk factors was developed to identify low-risk (< or =5%) patients. Obstructive coronary atherosclerosis was defined as 50% or more luminal narrowing in one or more major epicardial vessels, as determined by means of coronary angiography. RESULTS One hundred thirty-nine (19%) patients had obstructive coronary atherosclerosis. Independent predictors of coronary artery disease include age, male sex, hypertension, diabetes mellitus,and hyperlipidemia. Two hundred twenty patients were designated as low risk according to the logistic model. Of these patients, only 3 (1.3%) had single-vessel disease, and none had multivessel disease. The model showed good discrimination, with an area under the receiver-operating characteristic curve of 0.84. Cost analysis indicated that application of this model could safely eliminate 30% of coronary angiograms, corresponding to cost savings of $430,000 per 1000 patients without missing any case of high-risk coronary artery disease. CONCLUSION A model with standard clinical predictors can reliably estimate the prevalence of obstructive coronary atherosclerosis in patients undergoing mitral valve prolapse operations. This model can identify low-risk patients in whom routine preoperative angiography may be safely avoided.

Abstract
We examined changes in the levels of eicosanoids in blood and pulmonary lymph of anesthetized sheep undergoing acute anaphylaxis. Within 1-3 min of intravenous antigenic challenge of previously sensitized sheep, there were approximately 7-30-fold elevations in mean arterial plasma levels of thromboxane B2 and 6-ketoprostaglandin F1 alpha, respectively, as measured by RIA. Negligible changes in levels of these cyclooxygenase products were found in both nonsensitized sheep and in sensitized sheep treated with indomethacin before antigenic challenge. In contrast, no changes in levels of sulfidopeptide leukotrienes (SPLT) in pulmonary lymph were detectable by RIA during anaphylaxis in sensitized or nonsensitized sheep, but levels of SPLT in indomethacin-treated sensitized sheep increased more than fivefold above levels in lymph from both other groups of animals. The immunoreactive SPLT in lymph from indomethacin-treated sheep was accounted for as LTE4, as demonstrated by mobility on HPLC and absorbance at 280 nm. These results support the possibility that certain undesirable effects of nonsteroidal antiinflammatory drugs, such as cardiopulmonary reactions in aspirin-sensitive individuals, and impaired renal and cardiac function during therapy with these drugs, may be related in part to augmented synthesis of the 5-lipoxygenase pathway products, especially those of the sulfidopeptide class. Increased LT production could also limit the antiinflammatory effectiveness of these drugs in many disease states.

Abstract
Although several studies have described the status of the coronary arteries by angiography in patients with mitral stenosis (MS), few necropsy studies of the coronary arteries in these patients are available. The present report describes in detail the amounts of narrowing by atherosclerotic plaque of the 4 major epicardial coronary arteries in 76 necropsy patients, aged 31 to 79 years (mean 53) with clinically isolated MS (with or without associated mitral regurgitation but without aortic valve dysfunction). Of the 76 patients, greater than or equal to 1 major coronary artery was narrowed greater than 75% in cross-sectional area (XSA) in 38 (50%) and in 10 of the 38 patients greater than or equal to 1 major coronary artery was totally occluded or nearly so (greater than 95% XSA narrowing). A higher percent of the 29 men had significant (greater than 75% XSA) coronary narrowing than did the 47 women (62 vs 44%) and the men had more major coronary arteries significantly narrowed compared with the women (31 of 116 arteries [27%] vs 33 of 188 arteries [18%]). The 4 major coronary arteries in the 76 patients were divided into 5-mm segments and examined histologically: of the 3,124 segments (41 per patient), 620 segments (20%) were narrowed 0 to 25% in XSA, 1,826 (58%) were narrowed 26 to 50%, 470 (15%) were narrowed 51 to 75%, 188 (6%) were narrowed 76 to 95%, and 20 segments (1%) were narrowed 96 to 100% in XSA. The percent of segments narrowed greater than 75% in XSA was 9% in the men and 5% in the women.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Ninety-six consecutive patients older than 40 years with severe mitral stenosis were retrospectively analyzed to determine the relation of angina pectoris (AP) and coexistent coronary artery disease (CAD). Of the 96 patients, 27 (28%) had angiographically significant CAD, 10 (37%) with AP and 17 (63%) without AP. Of the 96 patients, 21 had AP, 10 (48%) with angiographically significant CAD and 11 (52%) without (CAD). Of 75 patients without AP, 17 (23%) had angiographically significant CAD AP had a specificity of 84% and a sensitivity of 37% in its ability to detect significant CAD. The pulmonary artery systolic, diastolic and mean pressures and the pulmonary vascular resistance did not differ between patients with and those without AP (p greater than 0.05). It is concluded that coexistent CAD is commonly found in patients older than age 40 with severe MS, and is usually clinically silent.

Abstract
This study analyzes the prevalence of coronary artery disease (CAD) among patients with rheumatic valvular heart disease (VHD) in Chile. Coronary angiography was performed in all patients referred to cardiac catheterization with VHD who were over age 50 years and who had angina or ECG signs of ischemia. A total of 100 patients entered the study. Significant CAD (greater than 50% obstruction) was found in 14% of the cases: 7% in patients with mitral valve disease (MVD), 18% in aortic valve disease (AVD), and 21% in combined mitral and aortic valve disease (MAVD). Angina was present in 14% of the patients with MVD, 63% with AVD, and 53% with MAVD. Only 57% of patients with CAD had angina pectoris; 20% with angina had CAD. Hemodynamic parameters and left ventricular ejection fraction were not correlated with the presence or absence of CAD. We conclude that in patients with valvular heart disease, the incidence of CAD is lower in Chile than previously reported in the English literature. We confirmed the fact that angina is often not associated with CAD, and that CAD is often present in the absence of angina.
