ObjectiveTo investigate the significance of using the term "high-normal blood pressure" and its intervention in the early stage. MethodsIn 1992 and 2007, we performed two similar investigations focusing on cardiovascular risk factors in 711 people in Chengdu city. Since 114 individuals were diagnosed with hypertension, 597 people without hypertension were eligible and divided into two groups:the normal-pressure[<120/80 mm Hg (1 mm Hg=0.133 kPa)] group and the high-normal blood pressure (systolic blood pressure 120-139 mm Hg and/or diastolic blood pressure 80-89 mm Hg) group. Data in the two investigations were compared to explore the relationship among high-normal blood pressure, cardiovascular disease (CVD) and hypertension. ResultsThe high-normal blood pressure group had a higher level of CVD risk factors both in 1992 and 2007, and the 15-year cumulative incidence of hypertension in the high-normal blood pressure group was higher than that of normal-pressure group (91.2% vs. 22.2%, P<0.001). After adjusting for serum lipid, body weight and other CVD risk factors, high-normal blood pressure could predict the progression into hypertension[HR=5.354, 95% CI (4.094, 7.002), P=0.001]. There was no statistics difference in CVD prevalence in the two groups in 1992, but in 2007 the prevalence of CVD tended to be higher in the high-normal blood pressure group (6.6% vs. 3.1%, P=0.052). ConclusionHigh-normal blood pressure is a special stage of blood pressure with high level of CVD risk factors and high potential to progress into hypertension. The term should be emphasized and intervention should be done in the early stage for high-normal blood pressure people to prevent from hypertension and CVD.
Objectives To analyze the risk factors for cardiovascular disease (CVD) in patients with chronic obstructive pulmonary disease (COPD) of different severities. Methods The study included 50 patients with mild-to-moderate COPD and 50 with severe-to-very severe COPD admitted between January 2014 and January 2016. Comorbidities were recorded on the basis of data obtained from medical charts and clinical evaluations. The Charlson comorbidity index was calculated, and the Hospital Anxiety and Depression Scale (HADS) score was determined in each subject. Results There were more prevalences of smoking, depression and dyslipidemia in the patients with mild-to-moderate COPD than those with severe-to-very severe COPD (all P<0.001). The prevalences of high blood pressure, diabetes mellitus, alcoholism, and chronic heart failure were not different significantly between the two groups. The Charlson comorbidity index and HADS scores were not different between the two groups. Conclusions Comorbidities are fairly common in COPD regardless of its severity. Certain risk factors for CVD, as smoking, dyslipidemia, and depression, appear to be more prevalent in patients with mild-to-moderate COPD.
There are various examination methods for cardiovascular diseases. Non-invasive diagnosis and prognostic information acquisition are the current research hotspots of related imaging examinations. Positron emission tomography (PET)/magnetic resonance imaging (MRI) is a new advanced fusion imaging technology that combines the molecular imaging of PET with the soft tissue contrast function of MRI to achieve their complementary advantages. This article briefly introduces several major aspects of cardiac PET/MRI in the diagnosis of cardiovascular disease, including atherosclerosis, ischemic cardiomyopathy, nodular heart disease, and myocardial amyloidosis, in order to promote cardiac PET/MRI to be more widely used in precision medicine in this field.
目的 阻塞性睡眠呼吸暂停低通气综合征（OSAHS）可引起心血管疾病发生增高，是高血压病及冠心病等的独立危险因素。打鼾是OSAHs的主要临床症状。本研究的主要目的是了解成都地区自然人群打鼾发生情况及其与心血管疾病危险因素的关系。 方法 2007年在成都市成华区采用随机抽样方法对男、女性共711人进行了心血管疾病危险因素调查[年龄45～80岁，平均（3.28 ± 6.25）岁，男性患者占所有患者的57.8%]，主要包括问卷调查、体格检查及血液学检查等，其中打鼾调查主要包括打鼾时间、次数及憋醒情况。将与打鼾相关的3个指标综合考虑后，计算出打鼾的严重程度，并分析了其与心血管疾病危险因素的关系。 结果 男性人群中打鼾率较女性高（62.0%、51.0%，P=0.003），且重度及极重度打鼾率也较女性高。随着打鼾的严重程度增加，体质量指数、血肌酐及尿酸等心血管疾病危险因素逐渐升高（趋势P均＜0.05），而高密度脂蛋白胆固醇逐渐降低（P=0.001）。另外，随着打鼾的严重程度增加，高血压患病率及收缩压也逐渐升高，但无统计学意义（趋势P=0.063，0.08）。 结论 成都地区中老年城镇人群的打鼾率较高，且男性高于女性。另外，随着打鼾的严重程度增加，心血管疾病危险因素也逐渐升高。这提示我们在临床工作中，对于打鼾的患者需要加强心血管疾病危险因素的筛查及干预，以期减少它的发生发展。
Objective To explore the relationship between uric acid (UA) level and cardiovascular disease in patients with OSAHS and its clinical significance. Methods The electronic medical record system of the First hospital of Lanzhou University was used to collect 475 subjects who completed polysomnography (PSG) during hospitalization from January 2019 to May 2020. According to the Guidelines for the Diagnosis and Treatment of Obstructive Sleep Apnea Hypopnea Syndrome (Basic Version), the patients were divided into four group: control group [apnea-hypopnea index (AHI) <5 times/h, n=96], mild group (5≤AHI≤15 times/h, n=130), moderate group (15<AHI≤30 times/h, n=112), and severe group (AHI>30 times/h, n=137). The age, gender, body mass index (BMI), smoking history, drinking history, hypertension, diabetes mellitus, cardiovascular disease and biochemical indexes [including triglyceride, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, glucose, UA, blood urea nitrogen (BUN), serum creatinine, lactate dehydrogenase, homocysteine], PSG indexes were observed and compared among the four groups, and the differences were compared by appropriate statistical methods. Binary logistic regression model was used to evaluate the correlation between various risk factors and cardiovascular disease. Results There were statistically significant differences in age, gender, BMI, drinking history, hypertension and cardiovascular disease among the 4 groups (P<0.05). The levels of UA and BUN in mild, moderate and severe groups were higher than those in the control group, with statistical significance (P<0.05). With the increasing of OSAHS severity, the level of UA increased. There was statistical significance in the incidence of cardiovascular disease among the four groups (P<0.05), and the highest incidence of arrhythmia was found among the four groups. And the incidence of cardiovascular disease increases with the increasing of OSAHS severity. Binary Logistic regression analysis showed that the risk factors for cardiovascular disease in OSAHS patients were age, UA and BUN (P<0.05). Conclusions The occurrence of cardiovascular disease in OSAHS patients is positively correlated with the severity of OSAHS. The level of UA can be used as an independent risk factor for cardiovascular disease in OSAHS patients. Therefore, reducing the level of UA may have positive significance for the prevention and control of the prevalence and mortality of cardiovascular disease in OSAHS patients.
Cardiovascular disease is the number one cause of death worldwide. A large body of epidemiologic evidence suggests that regular physical activity (PA) and high levels of cardiorespiratory fitness can prevent the progression of atherosclerotic cardiovascular disease and reduce the incidence of cardiovascular events. "Physical activity, cardiorespiratory fitness, and cardiovascular health: a clinical practice statement of the ASPC" released in December, 2022 by the American Society for Preventive Cardiology (ASPC) and provided the most up-to-date guidance on the associations and mechanisms between PA and cardiorespiratory fitness, the development of exercise prescriptions, and exercise-associated cardiovascular risk. In this article, the main content of this guideline was interpreted, aiming to develop a more scientific exercise prescription for patients with cardiovascular disease.

Serum alkaline phosphatase (ALP) has long been used as a biomarker for the liver, kidney, and bone. Currently, increasing evidence suggests a correlation between serum ALP and cardiovascular disease (CVD). Research has shown that serum ALP affects endothelial cell function and induces changes in pyrophosphate through various mechanisms to accelerate vascular calcification and promote cardiac fibrosis. Therefore, this article reviews the potential value of serum ALP in CVD through relevant research, revealing the specific relationship between serum ALP and CVD, in order to provide new ideas for the prevention and treatment of CVD.
ObjectiveTo investigate the correlation between lipid accumulation product (LAP) and risk of ischemic cardiovascular disease (ICVD). MethodsThis cross-sectional study was performed among community residents from an urban community in Chengdu area between September 2011 and June 2012. Questionnaire survey was carried out. Each individual underwent biochemistry analysis and physical examination. In addition, brachial-ankle pulse wave velocity (BaPWV) and augmentation index (AI) were detected. Pearson correlation analysis was performed to explore the relationship between LAP and each cardiovascular risk factor. Liner regression model was used to analyze the relationship between LAP and ICVD. ResultsA total of 780 individuals with complete data were included in the analysis. LAP was correlated with blood pressure, total cholesterol, high density lipoprotein cholesterol, fasting blood glucose, and BaPWV (P＜0.05). LAP was associated with the risk of ICVD (r=0.253, P＜0.001). After being adjusted with sex, age and other cardiovascular risk factors, LAP was also correlated with the risk of ICVD (r=0.050, P＜0.001). ConclusionsHigh LAP is associated with elevated cardiovascular risks and subclinical vascular damage. In addition, LAP is correlated with ICVD risk, thus it may be used to predict the incidence of ICVD to some extent. However, as the correlation is weak, our study does not support the direct use of this indicator to predict ICVD. Large-sample studies based on different races and ages are needed.
