Chest pain experienced by patients with coronary artery disease can be partly due to gastroesophageal reflux‐induced chest pain (GERP). Empirical proton pump inhibitor (PPI) therapy has been recommended as an initial clinical approach for treating GERP. However, PPI use may lead to some health problems. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) may represent a noninvasive and cost‐effective approach for avoiding PPI misuse and for identifying the appropriate patients for the PPI trial test. The aim of this pilot study was to prospectively evaluate the association between GerdQ scores and PPI response in patients with coronary artery disease (CAD) and GERP to determine whether the GerdQ predicts the PPI response in patients with CAD and GERP and to further validate the clinical application value of the GerdQ. A total of 154 consecutive patients with potential GERP were recruited to complete a GerdQ with subsequent PPI therapy. Based on the PPI trial result, patients were divided into a PPI‐positive response group and a PPI‐negative response group. The difference in the GerdQ scores between the two groups was assessed. The receiver operating characteristic (ROC) curve of GerdQ score was drawn according to the PPI response as the gold standard. The ability of GerdQ to predict the PPI response was assessed. A total of 96 patients completed the entire study; 62 patients (64.6%) were assigned to the PPI‐positive response group, and 34 patients (35.4%) to the PPI‐negative response group. The GerdQ score of the PPI‐positive response group (8.11 ± 3.315) was significantly higher than that of the PPI‐negative response group (4.41 ± 2.743), and the difference was statistically significant (t = 5.863, P = 0.000). The ROC curve was drawn according to a PPI response assessment result with a score above 2 as the gold standard. The area under curve was 0.806. When the critical value of GerdQ score was 7.5, Youden index was up to 0.514, the diagnostic sensitivity was 0.661, and the diagnostic specificity was 0.853. A GerdQ score greater than 7.5 better predicts the response to the PPI trial therapy. There is a strong association between the GerdQ score and the response to PPI therapy. Higher GerdQ scores were predictive of a positive PPI response in CAD patients with GERP. The GerdQ may be a reasonable screening tool for GERP in patients with CAD who are prepared to accept PPI therapy. 相似文献

C-reactive protein as a marker for active coronary artery disease in patients with chest pain in the emergency room 总被引:7,自引:0,他引:7
BACKGROUND: Markers of inflammation, such as C-reactive protein (CRP), were found to be related to risk for cardiovascular disease (CVD) events in patients with angina pectoris. In addition, recent studies have shown that, in the case of atherosclerosis, increased CRP concentration reflects the inflammatory condition of the vascular wall. HYPOTHESIS: The study was undertaken to determine whether CRP levels in individuals with chest pain attending the emergency room (ER) may be used as a marker of active CVD. METHODS: Serum CRP level was measured in 226 of 326 consecutive patients (128 men, 98 women; mean age 61.3 +/- 5.9 years; range 19-87 years) referred to the ER with chest pain. The decision whether to admit orrelease the subjects was determined without taking the CRP level into account. Follow-up was then performed for 1 year. RESULTS: Eighty-four patients were admitted to the hospital. Of these, 9 with acute coronary syndrome (ACS) had very high levels of CRP (25-40 mg/l), 35 had had an acute coronary event within the preceding 3 months, with levels of CRP 14-20 mg/l. Only eight patients with nonsignificant CVD had elevated CRP levels. Twenty-eight subjects who were released from the ER had elevated CRP levels (7-14 mg/l); 8 of these, in addition to 4 subjects with normal CRP levels, had a late coronary event. CONCLUSION: This study indicates that in patients referred to the ER with chest pain and no other indication for hospitalization, a normal level of CRP suggests safe release. Most hospitalized patients with normal CRP will not have acute coronary syndrome. Patients who will develop early coronary events have very high CRP levels. High serum CRP level, after excluding other inflammatory sources, was proven to be a sensitive diagnostic and prognostic marker for significant coronary disease. 相似文献

Objective: To determine the response of physicians to a noncoercive prediction rule for the triage of emergency department patients
with chest pain.
Design: Prospective time-series intervention study.
Setting: A university hospital emergency department.
Participants/patients: 68 physicians, all of whom were responsible for the triage of at least one of 252 patients presenting to the emergency department
with a chief complaint of acute chest pain.
Intervention: A previously validated algorithmic prediction rule that was attached to the back of patient data forms in the emergency
department.
Measurements: Patients’ clinical data were recorded by the examining physician in the emergency department or by a research nurse blinded
to patient outcome. The physicians recorded their own estimates of the risk of acute myocardial infarction and their reactions
to the prediction rule in a self-administered questionnaire completed at the time of triage.
Main results and conclusions: The physicians reported that they looked at the prediction rule during the triage of 115 (46%) of the 252 patients. The
likelihood of using the prediction rule decreased significantly with increasing level of physician training. The most common
reasons given for disregarding the prediction rule were confidence in unaided decision making and lack of time. The physicians
reported that of the 115 cases for which the prediction rule was used, only one triage decision (1% ) was changed by it. Future
research should explore how prediction rules can be designed and implemented to surmount the barriers highlighted by these
data.

Chest pain is a common reason for presentation to the emergency department (ED). Absolute criteria for Acute Coronary Syndrome without ST elevation (NSTE-ACS) are lacking. An acute coronary syndrome (ACS) needs to be distinguished from a variety of other cardiac and non-cardiac diseases that may cause chest pain.For patients with confirmed ACS, several scoring methods can be applied in order to distinguish patients in the coronary care unit who may benefit most from therapies. The PURSUIT, TIMI, GRACE and FRISC risk scores are well validated with this respect. However, none of these risk scores has been used in the identification of an ACS in the emergency setting. The vast majority of patients with chest pain due to causes other than ACS were not evaluated in these trials. An evidence-based systematic stratification and policy for these patients does not currently exist.The more recently developed HEART score is specifically designed to stratify all chest pain patients in the ED. The HEART score was validated in a retrospective multicenter study and proved to be a strong predictor of event free survival on one hand and potentially life threatening cardiac events on the other hand. The HEART score facilitates risk stratification of chest pain patients in the ED. 相似文献

Background: In patients with non-cardiac chest pain (NCCP), the optimal duration of an empirical trial with a high-dose proton pump inhibitor (PPI) is unclear. We aimed to compare the efficacy of one-week and two-week PPI trial in patients with weekly or more than weekly NCCP and to determine its optimal duration for diagnosing gastroesophageal reflux disease (GERD)-related NCCP.
Methods: Forty-two patients with at least weekly NCCP were enrolled. The baseline symptoms were assessed using a daily symptom diary for seven days. Also, esophago-gastro-duodenoscopy and 24 h esophageal pH monitoring were performed for the diagnosis of GERD. Then, patients were treated with rabeprazole 20 mg twice daily for 14 days. To assess NCCP improvement during the PPI trial, the first week and the second week symptom diary were kept for 1–7 and 8–14 days. The PPI test was considered positive if a symptom score improved (50% compared to the baseline.
Results: There was no significant difference for a positive PPI test between GERD-related NCCP group ( n = 8, 50%) and non GERD-related NCCP group ( n = 6, 23%) during the first week of the PPI test. However, during the second week, GERD-related NCCP had a higher positive PPI test ( n = 13, 81%) than non GERD-related NCCP ( n = 7, 27%) ( P = 0.001) with a sensitivity and specificity of 81% and 62%, respectively.
Conclusions: The rabeprazole empirical trial was diagnostic for patients with GERD-related NCCP, and its optimal duration was determined to be at least two weeks. 相似文献

Estimated prevalences of panic disorder and depression among consecutive patients seen in an emergency department with acute chest pain 总被引:5,自引:0,他引:5
Kevin W. Yinclinc MD Lawson R. Wulsin MD Lesley Mussio Arnold MD Dr. Gregory W. Rouan MD 《Journal of general internal medicine》1993,8(5):231-235
Objective: 1) To determine whether the frequencies of panic disorder (PD) and depression (DEP) in an emergency department (ED) population
were comparable to those in other primary care groups; 2) to evaluate whether patients without the clinical diagnosis of acute
cardiac ischemia (ACI) had higher frequencies of these disorders; and 3) to identify characteristic clinical findings in patients
with PD or DEP.
Setting: An urban teaching hospital ED.
Patients: Three hundred thirty-four patients with acute chest pain were evaluated prospectively over an eight-week period. The cohort
participating (69%—229/334) completed psychiatric screening measures, including the Panic Disorder Self-Rating Scale, the
Beck Depression Inventory, and the Zung Self-Rating Anxiety Scale.
Measurements and main results: A symptom profile consistent with PD was identified in 17.5% of the patients (40/229), DEP in 23.1% (53/229), and either
disorder in 35% (80/229). The prevalences of PD were similar in those with and without ACI (19.4% vs 16.6%, respectively,
p>0.05). The likelihoods of one or more ED visits for chest pain in the previous year were significantly greater in those
with PD (57.5% vs 36%, p<0.05) and DEP (54% vs 35%, p<0.05) than in those without these psychiatric disorders.
Conclusion: This study suggests that approximately one in three patients presenting to the ED with acute pain has symptoms consistent
with a psychiatric disorder. These disorders occur frequently in both those with and those without acute cardiac ischemia,
and clinical variables may help identify these frequent ED utilizers.

BACKGROUND: Non-cardiac chest pain (NCCP) is a heterogeneous disorder. There is controversy about the associations between symptoms and causes in NCCP patients. The purpose of the present study was to evaluate the clinical usefulness of subgrouping according to characteristic symptoms in NCCP patients. PATIENTS AND METHODS: Fifty-eight patients were classified into two groups, as patients with typical reflux symptoms (group I, n = 24) and those without typical reflux symptoms (group II, n = 34). They underwent upper endoscopy, manometry, and 24-h esophageal pH monitoring. RESULTS: Twenty-four (41%) of the patients were diagnosed with gastroesophageal reflux disease (GERD) at upper endoscopy or 24-h esophageal pH monitoring. Eleven (19%) were diagnosed with GERD-associated esophageal motility disorder and 13 (22%) were diagnosed with non-GERD-associated esophageal motility disorder. The two groups did not differ significantly in age, sex, weight, smoking history, history of chronic alcoholism, or the severity, duration and frequency of symptoms. The sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio of group I for GERD-related NCCP were significantly higher than those of group II. Group I had a higher proportion of patients with GERD-associated esophageal motility disorder (55%) than non-GERD-associated esophageal motility disorder (23%). CONCLUSION: Typical reflux symptoms can be used to distinguish patients with GERD-related NCCP from patients with NCCP, and subgrouping according to characteristic symptoms may assist the diagnosis of these patients in Korea. 相似文献

Background and Aim: Little is known about non‐cardiac chest pain (NCCP) in young patients. We aimed to examine the proportion of gastroesophageal reflux disease (GERD) in young patients with NCCP compared to the average‐aged NCCP patients and to evaluate their symptomatic characteristics and the clinical efficacy of a 2‐week proton pump inhibitor (PPI) trial. Methods: Ninety‐six patients with NCCP ≥ 1/week were classified into the young‐aged (≤ 40 years, n = 38) and the average‐aged groups (> 40 years, n = 58). Typical reflux symptoms were assessed. The patients were defined into a GERD group and non‐GERD group according to reflux esophagitis on esophagogastroduodenoscopy and/or pathologic acid exposure on 24‐h esophageal pH monitoring. Then the patients were treated with 30 mg of lansoprazole bid for 14 days. Results: Nine patients (23%) in the young‐aged group and 22 patients (38%) in average‐aged group were diagnosed with GERD‐related NCCP (P = 0.144). The proportion of typical reflux symptoms was higher in the GERD group compared with the non‐GERD group in both age groups. A PPI test improved symptoms in the GERD group irrespective of age, but this improvement was not observed in non‐GERD group. Conclusions: In young NCCP patients, the prevalence of GERD was relatively low compared to average‐aged NCCP, but the difference was insignificant. The PPI test was very effective in diagnosing GERD in the NCCP patients in both age groups. Therefore, in young NCCP patients, if there is a negative response to a 2‐week PPI trial, the possibility of extra‐esophageal disease origin needs to be considered. 相似文献

Background: Patients with non-cardiac chest pain (NCCP) are referred for esophageal motility testing and pH monitoring since gastroesophageal reflux disease (GERD) and esophageal motility disorders are frequently encountered in these patients. Our aim was to determine the prevalence and distribution of these disorders and to identify predictors of abnormal esophageal function testing.Methods: We performed a retrospective study of NCCP patients who presented after a negative cardiac evaluation and underwent esophageal manometry, esophageal pH monitoring and upper endoscopy from January 2010 to January 2017.Key results: In a total of 177 patients, esophageal motility disorders were diagnosed in 31% and GERD in 35% of the patients. The most common diagnoses were ineffective esophageal motility (IEM) in 14.1%, jackhammer esophagus in 6.8%, diffuse esophageal spasm in 5.1% and achalasia in 2.3% patients. Older age [for every 5-year increment, odds ratio (OR) 1.2 (95% confidence intervals (CI) 1.00–1.3) p?=?.047] and dysphagia [OR 3.8 (95% CI, 1.9–7.5) p?.001] were predictors of esophageal motility disorders. Older age [for every 5-year increment, OR 1.2 (95% CI, 1.01–1.3) p?=?.032] was predictive of GERD. Abnormal esophageal testing was associated with male gender [OR 2.2 (95% CI, 1.04–4.6) p?=?.039], older age [for every 5-year increment, OR 1.2 (95% CI, 1.03–1.3) p?=?.016] and Caucasian race [OR 3.1 (95% CI, 1.1–8.7) p?.029].Conclusions: Approximately two thirds of patients presenting with NCCP have GERD or esophageal motility disorders. Esophageal function testing in NCCP should be considered in older patients, men, Caucasians and those presenting with dysphagia. 相似文献

The study group identified 107 patients who left against advice from the emergency departments of three university and four
community hospitals after presenting for evaluation of acute chest pain. In comparison with other emergency department patients
with acute chest pain, patients who left against advice had findings that suggested they were at higher risk for myocardial
infarction than patients for whom admission was not recommended but at lower risk than patients who consented to be admitted.
Specific follow-up plans were made at the time of evaluation for 45 patients (42%). Survival data were obtained at 48–72 hours
for 104 patients (97%) and at one month for 101 patients (94%). Fourteen patients (12%) were hospitalized within three days
of their original emergency department visits, and three patients had documented acute myocardial infarctions. The only death
within one month was that of a patient who died suddenly out-of-hospital later on the day of his emergency department visit.
The authors conclude that patients who left against medical advice had presentations and prognoses that were in between those
of patients for whom admission was not recommended and those of patients who consented to be admitted.

Objective: To determine the prevalence and predictors of nonattendance in an ACHD
outpatient clinic, and to examine the relationship between nonattendance and emergency department (ED) visits, hospitalizations, and death.
Methods: Patients ≥ 18 years who had scheduled appointments at an ACHD outpatient clinic between August 1, 2014 and December 31, 2014 were included. The primary outcome of interest was nonattendance of the first scheduled appointment of the study period, defined as “no-show” or “same-day cancellation.” Secondary outcomes of interest were ED visits, hospitalizations, and death until December 2017.
Results: Of 527 scheduled visits, 55 (10.4%) were nonattended. Demographic and socioeconomic characteristics such as race, income, and insurance type were associated with non-attendance (all P values < .05), whereas age, gender, and disease complexity were not. On multivariable analysis, predictors of nonattendance were black race (adjusted odds ratio [AOR] 4.95; P < .001), other race (AOR 3.54; P = .003), and history of no-show in the past (AOR 4.95; P < .001). Compared to patients who attended clinic, patients with a nonattended visit had a threefold increased odds of multiple ED visits and a significantly lower rate of ED-free survival over time. There were no significant differences in hospitalizations or death by attendance.
Conclusion: ACHD clinic nonattendance is associated with race and prior history of no-show, and may serve as a marker of higher ED utilization for patients with ACHD. 相似文献

Objectives: Esophageal disease may mimic acute anginal pain. However, the prevalence of gastroesophageal reflux in the acute setting of patients with clinically unstable angina (UA) pectoris is not known. The aim of this study was to determine the co‐existence of coronary artery disease (CAD) and gastroesophageal reflux in UA, and to study the feasibility of esophageal investigation in the chest pain unit. Design: 22 patients with clinical UA and confirmed CAD were monitored by continuous vector cardiography and pH‐measurement during 24?h of observation. Symptoms of chest pain and episodes of ischemia and reflux were recorded. Results: 11 patients (50%) showed abnormal gastroesophageal reflux and another three (14%) had an increased number of reflux episodes. pH‐measurements and esophageal manometry were well tolerated. Few chest pain episodes were recorded during the study period, and no association between chest pain, reflux, and ischemia could be shown. Conclusion: Esophageal reflux is common in patients with UA and established CAD. As reflux‐related chest pain may imitate angina pectoris, it is clinically important that gastroesophageal examination in patients with UA seems to be feasible and well tolerated in the ‘acute setting’. 相似文献

BACKGROUND AND HYPOTHESIS: Noninvasive risk stratification for coronary artery disease (CAD) isless accurate in women than in men. Based on recent reports that gender-specific exercise electrocardiogram (ECG) parameters predict CAD, we evaluated the independent predictive value of the resting ECG for angiographic CAD in women with chest pain. METHODS: Women (n = 850, mean age 58 years) with chest pain in the NHLBI Women's Ischemia Syndrome Evaluation (WISE) underwent 12-lead ECG testing and quantitative coronary angiography. RESULTS: Significant angiographic CAD (> or = 50% stenosis in > or = 1 coronary) was present in 39% of women. Q waves in < or = 2 contiguous ECG leads were present in 107 women (13%), including 49 of 657 (7%) without history of infarction. Among 585 women without prior infarction orrevascularization, 48% of those with Q waves in contiguous leads versus 26% of others, had significant CAD (p = 0.003; odds ratio [OR] = 2.5, 95% confidence interval [CI] = 1.3-4.8). Women with Q waves in < or = 2 inferior ECG leads were particularly likely to have CAD (63 vs. 26% of others, p < 0.001; OR = 4.6,95% CI = 2.0-10.8). Other ECG findings predictive of CAD were any ST-T abnormality (OR = 1.9,95% CI = 1.3-2.8) and T-wave inversion (OR = 2.4, 95% CI = 1.3-4.2). In risk-adjusted analysis, inferior Q waves and T-wave inversion independently predicted significant CAD. When considered together with radionuclide perfusion test results, T-wave inversion on resting ECG added significant independent predictive value (OR = 2.8, 95% CI = 1.1-7.2, p = 0.03). CONCLUSIONS: Selected resting ECG parameters independently predict angiographic CAD in women with chest pain, including women who have also undergone radionuclide stress testing. Prospective studies should consider resting ECG parameters in diagnostic algorithms for CAD in women. 相似文献

Gastroesophageal reflux disease (GERD) causes a wide range of symptoms. Some patients present with typical symptoms such as heartburn and regurgitation and others with atypical symptoms such as chest pain. The mechanism responsible for the varying clinical presentation of GERD is still not fully elucidated. The aim of this study was to prospectively evaluate differences in central and local intraesophageal factors between patients with typical GERD symptoms and those with noncardiac chest pain (NCCP). Patients presenting with typical and atypical symptoms suspicious of GERD underwent upper endoscopy and 24‐hour pH monitoring with four sensors, each positioned at a different esophageal level. All patients completed GERD symptom, Hospital Anxiety and Depression Scale, and Symptom Stress Rating questionnaires. From January 2006 to December 2009, 50 patients were recruited, 29 with typical symptoms, and 21 with NCCP. Patients with proven GERD and NCCP had higher proximal extension of acid during reflux episodes than patients with typical symptoms. They were found to be older, had a shorter history of symptom onset, worse anxiety scores, and more endoscopic findings compatible with gastritis. Proximal extension of acid during the reflux episodes in patients with GERD presenting with NCCP may play a role in symptom generation. 相似文献

BACKGROUND: The rising cost of services provided by hospital emergency departments is of major concern. Attempts to reduce the costs of emergency cardiac care have thus far focused primarily on medical and administrative management in the hospital. The role of the patient in appropriate prehospital decision-making has been generally ignored. HYPOTHESIS: Membership in "Shahal" (an integrative telemedicine system) may have beneficial effects on patient decision-making and national health costs. METHODS: During a 6-month period, a random group of subscribers who had called for medical assistance during the previous 24 h were asked what action they would have taken had they not been Shahal subscribers. All study patients were followed for at least 7 days. RESULTS: In all, 1,608 subscribers (age 71 +/- 13 years) were included. Of these, 514 replied that they "would have waited," 363 "would have contacted their physicians," and 731 "would have sought emergency department care." Of the presenting medical problems, 86% were resolved without utilizing hospital facilities. A mobile intensive care unit was dispatched in 412 (26%) cases. A cost estimate of abuse indicated that the service resulted in a savings to the national economy of approximately $830,000 per 10,000 members per year.

在急诊科设立胸痛中心对胸痛患者诊疗时间的影响 总被引:1,自引:0,他引:1
目的在急诊科设立胸痛中心并研究其对急性胸痛患者诊疗时间的影响。方法在急诊科设立急性胸痛中心,每周开诊3d,时间随机确定,其余时间由急诊科按常规流程对胸痛患者进行诊疗,由研究者对急性胸痛患者的病因和诊疗时间进行注册登记。结果2006年1月至2007年12月因急性非创伤性胸痛就诊北京军区总医院急诊科或胸痛中心的患者共696例,心源性胸痛244例(35%),包括急性心肌梗死141例(20%),不稳定型心绞痛81例(12%),稳定型心绞痛17例(2.4%),主动脉夹层2例(0.3%),急性肺栓塞3例(0.4%);非心源性胸痛452例(65%),呼吸系统41例(6%),消化系统70例(10%),胸膜骨骼肌肉41例(6%),神经精神或其他299例(42%)。经胸痛中心诊治的胸痛患者的诊疗时间与常规诊疗流程相比都有所缩短。急性心肌梗死(70.1±31.7)min vs(115±40.5)min(P〈0.01);不稳定型心绞痛(228±54)min vs(264±78)min(P=0.02);非心源性胸痛(108±66)min vs (126±96)min(P=0.03)。结论急性胸痛患者的病因中,心源性者占35%,以急性心肌梗死和不稳定型心绞痛为主;非心源性者占65%。胸痛中心模式能显著缩短急性胸痛患者的诊疗时间。 相似文献
