RESUMO

BACKGROUND: Patients undergoing percutaneous coronary intervention (PCI) for unstable coronary syndromes have substantial emotional and spiritual distress that may promote procedural complications. Noetic (nonpharmacologic) therapies may reduce anxiety, pain and distress, enhance the efficacy of pharmacologic agents, or affect short- and long-term procedural outcomes. METHODS: The Monitoring and Actualization of Noetic Training (MANTRA) pilot study examined the feasibility of applying 4 noetic therapies-stress relaxation, imagery, touch therapy, and prayer-to patients in the setting of acute coronary interventions. Eligible patients had acute coronary syndromes and invasive angiography or PCI. Patients were randomized across 5 treatment groups: the 4 noetic and standard therapies. Questionnaires completed before PCI reflected patients' religious beliefs and anxiety. Index hospitalization end points included post-PCI ischemia, death, myocardial infarction, heart failure, and urgent revascularization. Mortality was followed up for 6 months after hospitalization. RESULTS: Of eligible patients, 88% gave informed consent. Of 150 patients enrolled, 120 were assigned to noetic therapy; 118 (98%) completed their therapeutic assignments. All clinical end points were available for 100% of patients. Results were not statistically significant for any outcomes comparisons. There was a 25% to 30% absolute reduction in adverse periprocedural outcomes in patients treated with any noetic therapy compared with standard therapy. The lowest absolute complication rates were observed in patients assigned to off-site prayer. All mortality by 6-month follow-up was in the noetic therapies group. In patients with questionnaire scores indicating a high level of spiritual belief, a high level of personal spiritual activity, a low level of community-based religious involvement, or a high level of anxiety, noetic therapies appeared to show greater reduction in absolute in-hospital complication rates compared with standard therapy. CONCLUSIONS: Acceptance of noetic adjuncts to invasive therapy for acute coronary syndromes was excellent, and logistics were feasible. No outcomes differences were significant; however, index hospitalization data consistently suggested a therapeutic benefit with noetic therapy. Of all noetic therapies, off-site intercessory prayer had the lowest short- and long-term absolute complication rates. Definitive demonstration of treatment effects of this magnitude would be feasible in a patient population about 4 times that of this pilot study. Absolute mortality differences make safety considerations a mandatory feature of future clinical trials in this area.

RESUMO

BACKGROUND: Percutaneous transluminal coronary angioplasty (PTCA) has become routine in the management of patients with stable angina pectoris and significant coronary stenoses, while medical management of such patients has declined. HYPOTHESIS: The purpose of the present study was to evaluate the outcome of 60 patients at the Virginia Heart Institute with stable angina pectoris, observed between 1976 and 1997, who had documented evidence of severe angiographic disease but were elected to be monitored and managed in an outpatient pharmacologic rehabilitation program. METHODS: Sixty patients with significant stenoses by coronary angiography (21 with single-vessel, 26 with double-vessel, and 13 with triple-vessel) without impaired ventricular function, exercise-induced ischemia or hypotension, limited exercise performance, malignant arrhythmias, or drug intolerance were enrolled in a program of pharmacologic rehabilitation and observed for an average of 7.2 years. RESULTS: Among the 60 patients, there were 6 deaths at a mean interval of 8.3 years. Two deaths were in patients ineligible for revascularization. Another patient who died had refused revascularization after new-onset left ventricular dysfunction, and another died intraoperatively during abdominal aortic aneurysm repair. Two patients died while exercising. Thirteen patients underwent follow-up catheterization for worsening angina; 11 of 13 showed progression, predominantly from new lesions. Four of 11 were referred for revascularization; 7 of 11 continued medical treatment; 49 patients were stable on medical therapy throughout the period of observation. CONCLUSION: Medical management of selected patients with significant coronary stenoses is safe and effective.

RESUMO

OBJECTIVE: Asthma and sinusitis are both inflammatory diseases of the respiratory epithelium, but to our knowledge no prospective analyses of CT of the sinuses in patients with acute asthma have been performed. The purpose of this study was to investigate the type and extent of abnormalities found on CT of the sinuses in patients with acute asthma. SUBJECTS AND METHODS: Sixty-five patients with acute asthma and 62 age-, race-, and sex-matched control subjects were enrolled in the emergency department. Limited coronal sinus CT was performed and scans were interpreted by a radiologist who was unaware of the patient's clinical condition. Scans were analyzed for the presence of mucosal thickening in the sinuses, ostiomeatal complexes, and nasal cavities. Scans were also assigned a CT score for total mucosal thickening. A CT score of 12 or more points indicated extensive disease. RESULTS: Mucosal thickening in the nasal passages (p < .001), ostiomeatal complexes (p < .05), and ethmoidal (p < .05) and sphenoidal sinuses (p < .05) was associated with acute asthma, but maxillary mucosal thickening was not (p = .44). CT scores differed significantly between asthmatic patients (7.7 +/- 0.8 points) and control subjects (4.1 +/- 0.4 points) (p < .001). Nineteen of the 65 asthmatic patients had extensive disease compared with two of the 62 control subjects (p < .001). Thirteen asthmatic patients with extensive disease underwent follow-up CT 5 months later, and 11 of the 13 patients showed improvement in CT score without having undergone specific therapy for sinusitis. CONCLUSION: Mucosal thickening in the nasal passages and sphenoidal, ethmoidal, and frontal sinuses is more common in patients with acute asthma than in control subjects. However, maxillary sinus mucosal thickening is no more common in asthmatic patients than in control subjects.

RESUMO

Expired nitric oxide (eNO) is a marker of airway inflammation that is increased in asthma. The present study was undertaken to examine the clinical utility of eNO as an aid in the assessment of asthma in the emergency department (ED). Fifty-two adult patients with acute asthma, 53 age- and sex-matched controls, and eight patients with stable asthma were enrolled. Subjects performed spirometry, their eosinophil counts and serum total IgE were measured, and a sample of mixed VC expirate was collected for measurement of NO. Mixed expired NO was 8.2 +/- 0.5 ppb in controls, 8.8 +/- 1.5 ppb in patients with stable asthma, and 15.0 +/- 1.0 ppb in patients with acute asthma. A significant difference in eNO was observed in patients with acute asthma and controls (p < 0.001). Twenty-three of the 52 patients with acute asthma versus two of 53 controls had an eNO >/= 15 ppb (p < 0.001). Expired NO concentration correlated with FEV1% (r = -0.42, p < 0.001) and with the peripheral blood eosinophil count (r = 0.34, p < 0.001) in the group of 60 patients with acute and stable asthma. The sensitivity of eNO > 10 ppb and eosinophilia (> 200 cells/microliter) was 90% in predicting airway obstruction (FEV1/FVC < 0. 8). No relationship of eNO was found to serum IgE, self- reported smoking, or glucocorticoid use. Measurement of eNO is a promising clinical tool for assessing acute asthma.

RESUMO

The prevalence of asthma has increased dramatically over the last 30 years, and the clearest evidence for the increase has come from population-based studies of school-aged children and young adults. The strongest established risk factors for asthma are family history and sensitization to one or more indoor allergens. Some studies suggest that the increase in asthma has been part of an overall increase in atopic disease. The American data, however, suggest that hay fever was already common in 1960. Thus the primary increase has been in wheezing among allergic children. It seems unlikely that increases in mite, cockroach, and domestic animal allergens have been sufficient to explain the scale or the consistency of the increase in asthma prevalence. The challenge is to identify a change that could have increased inflammation of the lungs or lowered the threshold for wheezing.

RESUMO

Lead distributions of peak ST-segment depression were compared between patients undergoing left circumflex artery percutaneous transluminal coronary angioplasty and exercise tolerance test. Localization of peak ST-segment depression to leads V2 or V3 was 96% specific and 70% sensitive for differentiating ischemia due to occlusion of left circumflex artery occlusion from nonocclusive ischemia.

RESUMO

Long angioplasty inflations have been reported using an autoperfusion system that delivers oxygenated blood distal to the balloon segment. The safety and efficacy of this system has been demonstrated in anatomically selected patients. The clinical use, however, is frequently to stabilize intimal dissection in unselected patients. We reviewed 12-lead continuous electrocardiographic (ECG) recordings in 40 patients in whom prolonged salvage with autoperfusion was attempted. Sub-optimal results were stabilized in 36 of 40, while 4 patients had urgent bypass. The presence of ischemia, as > or = 100 uV ST elevation over the 12 lead ECG, and the total ST deviation over all leads over the entire inflation period (total ischemic "burden") were compared within each patient between the longest standard balloon and autoperfusion inflations. Median duration of inflation was 3.03 min. with balloon vs. 15.6 min. with autoperfusion (p < 0.00002). Of the 40 patients, 35 (87%) had ECG ischemia with balloon vs. 18 (45%) with autoperfusion (p < .00002). Median severity of peak ST deviation was 321 uV with balloon vs. 132 uV with autoperfusion (p = 0.0001). Median extent of ST elevation was 3 leads with balloon vs. 0 leads with autoperfusion (p = 0.0001). Median total ischemic burden was similar with balloon (1173 uVmin) and autoperfusion (1083 uVmin, NS) despite the fivefold longer inflation duration with autoperfusion. Thus, in patients selected by clinical necessity rather than optimal anatomy, severity and extent of ST elevation were significantly reduced, although not entirely eliminated, by autoperfusion.
