OBJECTIVE: Low-density lipoprotein cholesterol (LDL-C) has been well known as the risk factor of coronary artery disease (CAD). However, the role of lipoprotein (a) [Lp(a)] in the development of CAD is of great interest but still controversial. Thus, we aim to explore the effect of Lp(a) on predicting the presence and severity of CAD in Chinese untreated patients, especially in combination with LDL-C. METHODS: We consecutively recruited 1,980 non-treated patients undergoing coronary angiography, among which 1,162 patients were diagnosed with CAD...

Recent studies have suggested that lipoprotein(a) [Lp(a)] is associated with cardiovascular disease (CVD). However, the contribution of Lp(a) to residual risk of CVD has not been determined in Chinese populations. We conducted a prospective study to evaluate the association between Lp(a) and the risk of major adverse cardiovascular events (MACEs) in patients with stable coronary artery disease (CAD) who received optimal medication treatment (OMT). The study enrolled 1602 patients with stable CAD from 5 hospitals in China...

AIMS: Coronary artery disease (CAD) is the leading cause of mortality and morbidity worldwide and one of the greatest threats to public health. Tenascin C (TNC) is an extracellular matrix glycoprotein that is found in low concentrations in normal tissues and is enhanced by a range of cardiovascular pathologies. This study aimed to evaluate the value of TNC in assessing the severity of atherosclerosis measured by the Gensini score. METHODS: A total of 157 patients with chest pains who underwent selective coronary angiography for suspected coronary atherosclerosis were enrolled...

We aimed to determine whether there is an association between cognition and the results of echocardiography and angiography, based on neuropsychological assessments. METHODS: We assessed the cognition of 85 patients who had recently undergone coronary artery angiography. We calculated the Gensini score for the coronary artery disease index. We also performed echocardiography to find indices of cardiac functioning. RESULTS: The lower left ventricular ejection fraction correlated with lower scores on visuospatial, executive function, processing speed/attention and verbal memory capacities (p ≤ 0...

Changes in intestinal flora in obese patients and intravascular C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) and coronary heart disease (CHD) were analyzed. A total of 75 cases of obese patients were divided into obesity (OB) alone (n=40) and OB with CHD group (n=35). There was no statistically significant difference in age, sex, pre-existing basic diabetes, history of hypertension, and body mass index (P>0.05). Results showed that total bacterial load of CHD was obviously higher than that of OB group...

BACKGROUND: Elevated lipoprotein(a) (Lp[a]) and low-density lipoprotein (LDL) cholesterol are important inheritable risk factors for premature coronary artery disease (CAD). Lp(a) mediates cardiovascular risk through prothrombotic, proinflammatory, and proatherogenic properties. The association of Lp(a) and LDL cholesterol with angiographic disease severity and complexity in patients with premature CAD has yet to be established. OBJECTIVE: To investigate the relationship of Lp(a) and LDL cholesterol with the severity and complexity of coronary artery lesions using the SYNergy between percutaneous coronary intervention with TAXUS and Cardiac Surgery (SYNTAX) and Gensini scores, in patients with premature CAD...

In-stent restenosis (ISR) is the most common complication associated with percutaneous coronary intervention (PCI). Although some studies have reported an association between lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) and ISR, not enough clinical validation data are available to support this link. Here, we report our cross-sectional study aimed at exploring the feasibility of LOX-1 as a biomarker for the prognostic diagnosis of patients undergoing PCI.Three groups were included: ISR group, including 99 patients with ISR diagnosed with coronary arteriography (CAG) after PCI; lesion group, comprising 87 patients with coronary artery stenosis (<50%) diagnosed with CAG after PCI; and control group, consisting of 96 volunteers with no coronary artery disease...

Background -The coagulation system is closely linked with vascular inflammation, although the underlying mechanisms are still obscure. Recent studies show that protease-activated receptor (PAR)-2, a major receptor of activated factor X (FXa), are expressed in both vascular cells and leukocytes, suggesting that PAR-2 may contribute to the pathogenesis of inflammatory diseases. Here we investigated the role of PAR-2 in vascular inflammation and atherogenesis. Methods -We generated apolipoprotein E-deficient ( ApoE-/- ) mice lacking systemic PAR-2 expression ( ApoE-/- PAR-2-/- )...

Diabetes mellitus (DM) is associated with more extensive coronary atherosclerosis and more vulnerable plaque phenotypes. However, DM should not be considered a homogeneous and purely binary entity in terms of risk assessment. We evaluated the impact of prediabetic status on coronary atherosclerosis burden in patients with first-time acute coronary syndrome (ACS) who underwent urgent coronary angiography. The patients were divided into DM, prediabetes, and control groups. The 3-vessel disease (TVD) rates and SYNTAX and Gensini scoring systems for defining atherosclerotic burden were compared...

BACKGROUND: Coronary artery disease (CAD) and osteoporosis (OP) are common diseases in postmenopausal women. In both cross-sectional and longitudinal epidemiologic studies, low bone mass has been related to increased frequency of CAD. However, available data on the relationship between bone mineral density (BMD) and severity of coronary lesions is limited. OBJECTIVE: To investigate association between the BMD and severity of coronary lesions assessed by Gensini score in postmenopausal women...

A novel single-photon emission computed tomography (SPECT) camera was developed to evaluate dynamic myocardial perfusion flow. However, it is unclear whether myocardial flow reserve (MFR) derived by dynamic perfusion SPECT using the novel SPECT camera (D-SPECT) reflects the severity of coronary atherosclerosis. In the present study, we therefore examined the relationship between MFR using D-SPECT and severity of coronary lesions. The study population comprised 40 patients who underwent both a myocardial dynamic perfusion SPECT study and invasive coronary angiography...

Whether prediabetes mellitus (Pre-DM) alone or combined with hypertension is an independent risk factor for cardiovascular disease has not been fully clarified. This study aimed to further confirm whether the relation of Pre- DM to cardiovascular disease differs between individuals with or without hypertension. A total of 7121 consecutive patients with angina-like chest pain who received coronary angiography were evaluated and 4193 patients with angiography-proven stable, new-onset coronary artery disease were enrolled into the study...

BACKGROUND: Reduced forced expiratory volume in 1 second percentage (FEV1%) predicted is closely related to cardiovascular mortality. However, evidence regarding the correlation between FEV1% predicted and the severity of coronary atherosclerosis observed on coronary angiography is still limited. We aimed to explore whether a decline in FEV1% predicted was associated with diffuse coronary atherosclerosis in hospitalized patients. METHODS: A cross-sectional study enrolling hospitalized patients with cardiovascular symptoms undergoing both coronary angiography and lung function testing was conducted...

The role of serum uric acid in coronary artery disease has been extensively investigated. It was suggested that serum uric acid level (SUA) is an independent predictor of endothelial dysfunction and related to coronary artery lesions. However, the relationship between SUA and severity of coronary atherosclerosis evaluated via endothelial dysfunction using peripheral arterial tone (PAT) and the reactive hyperhemia index (RHI) has not been investigated during a first episode of acute coronary syndrome (ACS). The aim of our study was to address this point...

Background: The diagnosis of coronary artery disease (CAD) in patients with LBBB represents a clinical challenge. The presence of fragmented QRS (fQRS) complex on surface ECG may be related to myocardial ischemia, scarring or fibrosis. Objectives: To investigate the relation between fQRS and the presence and severity of CAD in patients with LBBB. Patients and methods: 56 patients with symptoms suggesting CAD and complete LBBB were submitted to full history taking and clinical examination, complete 12-leads electrocardiography (ECG) to confirm the diagnosis of LBBB and to diagnose the fragmented wide QRS (f-wQRS) complex, echocardiography, and coronary angiography; lesions with ⩾70% narrowing in major epicardial artery or ⩾50% narrowing in the left main coronary artery were considered significant; and Gensini score was calculated...
