Symptoms of a first acute myocardial infarction in women and men

Background: Many studies have compared women and men for symptoms of acute myocardial infarction (AMI), but findings have been inconsistent, largely because of varying inclusion criteria, different study populations, and different methods.Objective: The purpose of this study was to analyze gender differences in symptoms in a well-defined, population-based sample of women and men who experienced a first AMI.Methods: Information on symptoms was collected from the medical charts of all patients with a first AMI, aged 25 to 74 years, who had taken part in the INTERGENE (Interplay Between Genetic Susceptibility and Environmental Factors for the Risk of Chronic Diseases) study. INTERGENE was a population-based research program on risk factors for cardiovascular disease. Medical charts were reviewed for each patient to determine the symptoms of AMI, and the prevalence of each symptom was compared according to sex.Results: The study included 225 patients with a first AMI: 52 women and 173 men. Chest pain was the most common symptom, affecting 88.5% (46/52) of the women and 94.8% (164/173) of the men, with no statistically significant difference between the sexes. Women had significantly higher rates of 4 symptoms: nausea (53.8% [28/52] vs 29.5% [51/173]; age-adjusted odds ratio [OR] = 2.78; 95% CI, 1.47–5.25), back pain (42.3% [22/52] vs 14.5% [25/173]; OR = 4.29; 95% CI, 2.14–8.62), dizziness (17.3% [9/52] vs 7.5% [13/173]; OR = 2.60; 95% CI, 1.04–6.50), and palpitations (11.5% [6/52] vs 2.9% [5/173]; OR = 3.99; 95% CI, 1.15–13.84). No significant gender differences were found in the proportions of patients experiencing arm or shoulder pain, diaphoresis, dyspnea, fatigue, neck pain, abdominal pain, vomiting, jaw pain, or syncope/lightheadedness. No significant differences were found in the duration, type, or location of chest pain. The medical charts listed numerically more symptoms in women than in men; 73.1% (38/52) of the women but only 48.0% (83/173) of the men reported >3 symptoms (age-adjusted OR = 3.26; 95% CI, 1.62–6.54).Conclusions: Chest pain is the most common presenting symptom in both women and men with AMI. Nausea, back pain, dizziness, and palpitations were significantly more common in women. Women as a group displayed a greater number of symptoms than did men.     

Association of secreted frizzled-related protein 4 (SFRP4) with type 2 diabetes in patients with stable coronary artery disease

Background

The interplay between the novel adipokine retinol-binding protein-4 (RBP4) and coronary artery disease (CAD) is still obscure. We investigated the relationship between RBP4 levels and the presence and severity of angiographically proven CAD and determined its possible role in acute myocardial infarction (AMI).

Methods

305 individuals with angiographically proven CAD (CAD-patients), were classified into 2 subgroups: 1) acute myocardial infarction (AMI, n = 141), and 2) stable angina (SA, n = 164). Ninety-one age- and sex-matched individuals without CAD, but with at least 2 classical cardiovascular risk factors, served as controls (non-CAD group). RBP4 serum levels were measured at hospital admission and were analyzed in relation to the coronary severity stenosis, assessed by the Gensini-score and the number of coronary narrowed vessels. Other clinical parameters, including insulin levels, HOMA-IR, hsCRP, glycaemic and lipid profile, and left-ventricular ejection fraction were also assessed.

Results

Serum RBP4 levels were significantly elevated in patients with CAD compared to non-CAD patients (39.29  ± 11.72 mg/L vs. 24.83  ± 11.27 mg/L, p < 0.001). We did not observe a significant difference in RBP4 levels between AMI and SA subgroups (p = 0.734). Logistic regression analysis revealed an independent association of CAD presence with serum RBP4 (β = 0.163, p = 0.006), and hsCRP (β = 0.122, p = 0.022) levels, in the whole study group. Among variables, hsCRP (β = 0.220), HDL (β = β0.150), and RBP4 (β = 0.297), correlated in both univariate and multivariate analysis with CAD severity (R² = 0.422, p < 0.001). Similarly, RBP4 concentrations increased with the number of coronary narrowed vessels (p < 0.05).

Conclusion

Patients with CAD, both SA and AMI, showed elevated RBP4 serum levels. Notably, increased RBP4 concentration seemed to independently correlate with CAD severity, but no with AMI.

Hot Flashes and Fatigue Relieved by Metformin

ObjectiveTo describe 3 patients with long-standing hot flashes, excessive sweating, and fatigue whose symptoms were ameliorated with metformin.MethodsIn this case series, we report the findings of laboratory evaluations, including assessments for thyroid, gonadal, adrenal, and pancreatic disorders, in 3 patients referred for endocrine evaluation. A 75-g oral glucose tolerance test with measurement of fasting and postprandial glucose and insulin concentrations was conducted. A trial of metformin, 500 mg twice daily, was initiated in all patients.ResultsEvaluation of factors that are associated with hot flashes and increased sweating did not establish the cause of the patients’ symptoms. The 3 patients had normal glucose tolerance test results and hyperinsulinemia. Metformin therapy markedly relieved the symptoms in all patients.ConclusionsHyperinsulinemia without hypoglycemia may produce a sympathoexcitatory response that manifests as hot flashes and increased sweating. Metformin may have sympathoinhibitory actions that alleviate these symptoms. (Endocr Pract. 2009;15:30-34)     

小儿病毒性腹泻的临床预后及危险因素分析

目的:探讨小儿病毒性腹泻的临床预后及危险因素。方法:纳入病例是2018年1月至2019年12月本院收治的200例小儿病毒性腹泻患者,回顾性分析其临床资料,分析小儿病毒性腹泻的临床特点。根据疾病痊愈情况分组,将128例痊愈患者作为实验组,72例未痊愈患者作为参照组,Logistic分析小儿病毒性腹泻患者疾病痊愈的危险因素。结果:200例患者中,HAstV感染121例,占60.50%;HAD感染36例,占18.00%;HUCV感染15例,占7.50%;HRV感染10例,占5.00%;混合感染18例,占9.00%。HAstV类型病毒性腹泻患者临床症状以呼吸道症状、发热、呕吐为主;HAD类型病毒性腹泻患者临床症状以发热、呕吐为主;HUCV类型病毒性腹泻患者临床症状以呼吸道症状、发热为主;HRV类型病毒性腹泻患者临床症状以发热、呕吐为主;混合感染类型病毒性腹泻患者临床症状以呼吸道症状、发热、呕吐为主。年龄、中枢神经损害、心肌损害、近1 w是否接触过腹泻是小儿病毒性腹泻患者疾病痊愈的危险因素,P0.05。结论:小儿病毒性腹泻不同感染类型,临床症状各不相同。小儿病毒性腹泻患者预后与年龄、中枢神经损害、心肌损害、近1 w是否接触过腹泻有着极为密切的联系,应当引起临床重视与关注。     

Presence and extent of cardiac computed tomography angiography defined coronary artery disease in patients presenting with syncope

Background

In syncope patients, presence of coronary artery disease (CAD) is associated with poor prognosis. However, data concerning CAD prevalence in syncope patients without known cardiovascular disease are lacking. Therefore, the aim of this study was to investigate presence and extent of CAD in syncope patients.

Methods

We included 142 consecutive patients presenting with syncope at the outpatient cardiology clinic who underwent coronary computed tomography (CT) angiography. Syncope type was ascertained by two reviewers, blinded for coronary CT angiography results. Of the patients, 49 had cardiac syncope (arrhythmia or structural cardiopulmonary disease) and 93 had non-cardiac syncope (reflex [neurally-mediated], orthostatic or of unknown cause). Cardiac syncope patients were compared with matched stable chest pain patients regarding age, gender, smoking status, diabetes mellitus type 2 and systolic blood pressure.

Results

Distribution of CAD presence and extent in cardiac and non-cardiac syncope patients was as follows: 72% versus 48% any CAD; 31% versus 26% mild, 8% versus 14% moderate and 33% versus 7% severe CAD.Compared with non-cardiac syncope, patients with cardiac syncope had a significantly higher CAD presence and extent (p = 0.001). Coronary calcium score, segment involvement and stenosis score were also higher in cardiac syncope patients (p-values ≤0.004). Compared to the chest pain control group, patients with cardiac syncope showed a higher, however, non-significant, prevalence of any CAD (72% versus 63%) and severe CAD (33% versus 19%).

Conclusion

Patients with cardiac syncope show a high presence and extent of CAD in contrast to non-cardiac syncope patients. These results suggest that CAD may play an important role in the occurrence of cardiac syncope.
