Abstract Background: With the rapid change of lifestyle, the incidence of coronary artery disease (CAD) was gradually rising among young people, but the specific reason for it was unclear. There were many evidences suggesting free fatty acids (FFAs) were involved in progression of CAD, our study was designed to discuss the relationship between serum FFAs and acute coronary syndrome (ACS) and the complexity of coronary artery disease in premature coronary artery disease (pCAD) patients. Methods: 502 pCAD patients suffering from ACS confirmed by coronary angiography in Beijing Anzhen Hospital from January to December 2019 were enrolled (ACS group), and 141 patients of the same age whose coronary angiography result was negative were selected during the same period (control group). The clinical data and characteristics of CAD among two groups were gathered and compared.Results: The level of FFAs in ACS group was significantly higher than control group (P < 0.001), and the value of FFAs in AMI group was higher than UA (P < 0.05) in both genders. The concentration of FFAs in three-vessel disease group was higher than double-vessel disease group and double-vessel disease group was higher than single-vessel disease group. The linear correlation coefficient between FFAs value and SYNTAX score was 0.370, P < 0.001. The AUC of FFAs to diagnose ACS was 0.798 (0.743-0.853, P < 0.001) in males, and 0.738 (0.677-0.800, P < 0.001) in females. Logistic regression analysis showed that elevated level of FFAs [odds ratio (OR) = 7.06, 95% confidence interval (CI) 4.40-11.33, P < 0.001] was independently associated with ACS. Conclusions: Concentration of FFAs is an independent risk factor associated with the incidence of ACS in pCAD patients and positively correlated with the complexity of CAD.

Purpose: To investigate the levels of pregnancy-associated plasma protein A (PAPP-A) or insulin-like growth factor -1 (IGF-1) in patients with acute coronary syndrome. Methods: Serum PAPP-A and IGF-1 was measured with biotin–tyramide-amplified enzyme immunoassay and Enzyme Linked Immuoserbent Assay, respectively, in patients with ST elevation acute myocardial infarction (STEMI, n=12), unstable angina (UAP, n=15), and stable angina (n=15). PAPP-A and IGF-1 was also measured in 16 healthy subjects (control group). Results: The serum levels of PAPP-A in the STEMI (16.9±10.3 mIU/L) and UAP group (15.2±10.5 mIU/L) were higher than in the stable angina (8.5±3.1 mIU/L) or control group (8.4±2.0 mIU/L, P < 0.01). The serum levels of IGF-1 in the STEMI (132.3±40.9 µg/L) and UAP group (127.3±36.0 µg/L) were also higher than in the stable angina (44.9±18.5 µg/L) or control group (67.7±24.5µg/L, P < 0.01). There were no differences in serum levels of PAPP-A or IGF-1 among the single, double and three vessel lesion groups. The serum levels of PAPP-A (19.9±10.1 mIU/L) and IGF-1 (153.2±52.4 µg/L) after PCI were higher than those before PCI (15.1±10.0 mIU/L and 91.4±51.0 µg/L, respectively, P < 0.01). A positive correlation was found between PAPP-A and IGF-1 levels in the STEMI and UAP group before PCI (r=0.48?P < 0.01). Conclusion: PAPP-A and IGF-1 are elevated in patients with acute coronary syndrome. They may be used as biomarkers for vulnerable plaques in patients with coronary artery disease. Whether post-PCI elevation of IGF-1 can be used to predict restenosis of coronary arteries remains to be seen.

The clinical presentation and angiographic findings of coronary artery disease (CAD) varies from diabetic and non-diabetic patients and varies with the age of presentation. Coronary artery disease in patients below the age of 45 is a special subset. The objective of this study is to compare the clinical and angiographic profile in patients with the acute coronary syndrome (ACS) with diabetes mellitus (DM) and without DM below the age of 45 years. Clinical Presentation of coronary artery disease in young patients with various risk factors differs, which plays an important role in management strategies. This was conducted through internet search on PubMed and ProQuest database from 2000 to until 2019. Key words used for searching are acute coronary syndrome, young diabetics, and clinical, angiographic profile. An important exclusion criterion is studies which included type one diabetic patients. Totally 35 papers were reviewed. Pattern of involvement of coronary arteries as assessed by the coronary angiographic study is found to be different in younger CAD patients. Atypical clinical presentation and distinct angiographic finding are common in diabetics below the age of 45. In most of the studies single vessel disease (SVD) is the most common angiographic finding in young CAD and non-diabetics. While the diabetics showed the more diffuse pattern of double vessel disease (DVD).

Objective: The exchange of apolipoprotein A-I between lipid-associated and lipid-free states is a key step in reverse cholesterol transport and is representative of HDL’s functional status. Reduced HDL-apoA-I exchange (HAE) is associated with the presence of cardiovascular disease. To build on this observation, we investigated the hypothesis that HAE in a coronary artery disease-identified patient decreases with increased coronary artery disease instability. Method: HAE was measured by electron paramagnetic resonance spectroscopy (EPR), wherein nitroxide-labeled lipid-free apoA-I is introduced into apolipoprotein B-depleted plasma, incubated at 37°C and measured. When added to plasma, the nitroxide-labeled apoA-I specifically interacts with HDL and displaces resident apoA-I. The EPR spectrum reports the population of lipid-bound, spin labeled apoA-I, which is directly proportional to the amount of resident apoA-I displaced. The relative level of apoA-I displaced is representative of the plasticity of HDL and its ability to make lipid-poor apoA-I available for ABCA1-mediated cholesterol efflux. We measured HAE in the plasma of three groups: stable coronary artery disease (n=22), 3 months following acute coronary syndrome (n=19), and a control group with no history of coronary artery disease (n=15). Results: HAE was significantly lower in both the stable coronary artery disease and acute coronary syndrome groups, compared to the control group (P<0.001 and, P<0.0001, respectively). Remarkably, the ACS subjects also had significantly lower HAE compared to those with stable CAD (P<0.01). By comparing HAE to apoA-I and HDL-C levels, we observed that stable CAD and ACS subjects have lower HAE per milligram/deciliter of apoA-I, consistent with a qualitative deficiency in their apoA-I. Conclusions: HAE activity is a by-product of apoA-I qualitative status, which is inversely correlated with coronary artery disease stability.

Background. The expression of the platelet-derived growth factor (PDGF), angiopoietin-1 (Ang-1) in patients with coronary artery disease of different studies was inconsistent. This study was to investigate the expression of the PDGF and Ang-1 in peripheral blood and coronary artery in patients with acute coronary syndrome (ACS) and the relationship between the expression of the PDGF and Ang-1 and the severity of coronary artery disease. Methods. A total of 81 patients with acute coronary syndrome undergoing coronary angiography were enrolled from September 2012 to December 2013. Patients with ACS included 61 patients with acute myocardial infarction (AMI group) and 20 patients with unstable angina pectoris (UAP group). The 29 patients who were hospitalized for chest pain undergoing coronary angiography without stenosis and with TIMI level 3 blood flow were selected as the control group. During coronary arteriography (CAG) or percutaneous coronary intervention (PCI), blood in the peripheral artery and in the local coronary artery was collected from all the patients. Serum PDGF and Ang-1 levels were measured by ELISA. We calculated the Gensini score of each patient with CHD according to the result of CAG. Patients with ACS were followed up, and the major adverse cardiovascular and cerebrovascular adverse events were recorded. Results. In peripheral blood, the concentration of the PDGF was significantly elevated in the ACS group than that of the control group. The level of the PDGF in the AMI group was significantly higher than that in the UAP group. In coronary artery blood, the level of the PDGF in the ACS group was significantly higher than that of the UAP group. There was no significant difference in the concentration of Ang-1 in peripheral blood between patients with coronary heart disease and the control group. The concentration of Ang-1 in the coronary artery was significantly lower than that in peripheral blood. The coronary Ang-1 concentrations in the ACS group were significantly higher than those in the UAP group. The concentrations of the PDGF and Ang-1 in peripheral and coronary artery blood were positively correlated with the severity of coronary lesions. Patients with MACCE had higher PDGF and Ang-1 levels in the coronary sinus. Conclusion. The serum PDGF concentration in patients with acute coronary syndrome was significantly increased, especially in the local coronary artery. The serum Ang-1 in the coronary artery was significantly increased in patients with acute myocardial infarction and was related to the degree of coronary artery stenosis. Coronary sinus PDGF and Ang-1 levels can reflect the severity of lesions in patients with acute coronary syndrome.

BackgroundCoronary artery disease (CAD) in the younger adult population has been commonly under-represented in clinical practice and research studies given its early latent asymptomatic course, in addition to the underestimation of this population's CHD lifetime risk by commonly used CHD risk predictors such as Framingham's score.ObjectiveTo assess the risk factor profile for premature coronary artery disease CAD and ACS presentation in younger adults.MethodsRetrospective chart analysis of 393 patient's ≤40 years old admitted from 2005 to 2014 for chest pain and underwent coronary angiography. The implication of modifiable risk factors and non-modifiable risk factors were evaluated in those with obstructive CAD (LM stenosis of ≥50% or stenosis of ≥70% in a major epicardial vessel), non-obstructive CAD (≥1 stenosis ≥20% but no stenosis ≥70%) and normal coronaries (no stenosis >20%). Additionally we evaluated the impact of the same risk factors on ACS presentation (NSTEMI vs STEMI) and the extent of CAD (single-vessel/multi vessel).ResultsOf 9012 patients who underwent cardiac catheterization, 393 (4.3%) patients were ≤40 years old.Out of 393, 212 (54%) had CAD (153 obstructive versus 59 non-obstructive) while 185 (46%) had normal coronaries.Fifty two (25%) patients presented with STEMI while 140 (66%) patients presented with NSTEMI.Of 153 patients with obstructive CAD, 87 (57%) patients had single vessel disease vs 66 (43%) multiple vessel disease.When compared to patients with normal coronaries patients with CAD were more likely to be smokers (p<0.0001), dyslipidemia (p<0.0001), Diabetic (p<0.0001) cocaine users (p 0.4) have a family history of premature CHD (<0.0001) and be males (p<0.0001) (figure=1).Smokers were more likely to present with acute coronary syndrome; 5 times more likely to present with STEMI (p<0.0001) and 1.7 with NSTEMI (p 0.0003) compared to the control group.When compared head to head, smokers were 2.2 times more likely to present with STEMI compared to NSTEMI (p<0.001).Smoking also, alone and with another risk factor increased the risk of obstructive versus no obstructive CAD (p=0.04 and 0.015, respectively).No significant difference was noted in the single vessel vs multi vessel CAD subgroups.Coronary artery disease was highest in South Asian population (38.4%), followed by Hispanic (13.7%), African-American (10%) and Caucasian (9%). The main in risk factors in African–American was Hyperlipidemia +/− Diabetes (47.8%) while the main risk factors in Hispanic and white were smoking alone (24.14% and 47.4% respectively). In East Asia population, Smoking with hyperlipidemia was the main risk factors (44%).ConclusionIn our population of young adults, smoking as a single risk factor was the most prevalent for earlier CAD. It was also associated with more STEMIs and obstructive CAD. Healthcare intervention in the general population through screening, counseling and education regarding smoking cessation is warranted to reduce premature coronary artery disease.

Background: Coronary artery disease is a devastating disease precisely because an otherwise healthy person in the prime of life may die or become disabled without warning. The objectives were to study the clinical profile, risk factors prevalence, angiographic distribution and severity of coronary artery stenosis in acute coronary syndrome (ACS) patients admitted in Cardiology Department of Cardiology Katuri Medical College & Hospital, Guntur.Subjects and Methods:A total of 208 patients of ACS were analyzed for various risk factors, angiographic patterns and severity of coronary artery disease in smokers vs non-smokers at Katuri Medical College, Andhra Pradesh.Results:Study group consisted of 208 subjects, of which 108(51.9%) subjects were smokers including all forms of tobacco use and 100(48.1 Out of 108 study subjects in  the  smokers group, family history of CAD  was present in 21(19.4%) subjects. Killip class is not applicable to 13 (12%) study groups as they presented with Unstable Angina with ECG changes. Killip class 1 was most common presentation (67.6%) in smokers. 28 patients (25.9%) had LV dysfunction with EF < 50% by echocardiography. 80 patients (74.1%) had normal LV function. The mean EF was 55.56+/-10.16%. The median EF was 56.5%. LAD was type 3 in 100 (92.6%) patients and type 4 in 8 (7.4%) patients   out of 108 study subjects.LAD type 3 was statistically significant with P value < 0.05 when compared with LAD type 4. No statistically significant difference was seen with respect to the Normal coronary arteries as CAG diagnosis between smokers and non-smokers(6.7% versus 8%,p>0.1,Not significant).Conclusion: Smokers were predominantly male and around 3 years younger than non-smokers. Diabetes mellitus and hypertension were less common among smokers and single-vessel disease was the more common angiographic finding for smokers as compared to 3-vessel disease for non-smokers. ST-segment elevation myocardial infarction in smokers despite younger age and the low atherosclerotic risk profile, in our region, emphasize the need for nicotine addiction management and smoking cessation campaigns at large and for pre-discharge counseling.

Background and Aims: Acute coronary syndrome (ACS) refers to a group of clinical symptoms consistent with new onset or worsening ischemic symptoms. ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA) are the three types of ACS. The objectives were to study the risk factors prevalence, angiographic distribution and severity of coronary artery stenosis in ACS among patients admitted in Cardiology Department of Manmohan Cardiothoracic Vascular and Transplant Center (MCVTC). Methods: This is a restrospective study of 419 ACS patients admitted and treated in MCVTC from November 2017 to October 2018. Patients were divided into STEMI, NSTEMI and UA then analyzed for various risk factors, angiographic patterns and severity of coronary artery disease. Results: Mean age of presentation was 59.3Å}12.8 years. Majority were male 317(75.7%). Most patients had STEMI 252 (60.1%) followed by NSTEMI 98 (23.4%) and UA 69 (16.5 %). Risk factors: smoking was present in 241 (57.5%), hypertension in 212 (50.6%), diabetes in 144 (34.4%), dyslipidemia in 58 (13.8%). Single-vessel disease was present in 34.6 % patients, double- vessel disease was present in 27.44 % patients and triple vessel disease was present in 26.3 % patients, left main disease in 1.4 % patients. Normal coronaries were present in 6.4% patients and minor coronary artery disease in 3.8 % patients. Conclusions: STEMI was the most common presentation. Three quarters of ACS were male patients. Smoking was most prevalent risk factor. Single vessel involvement was the most common CAG finding in all spectrum of ACS. Diabetic patients had more multivessel disease.

Background: Acute coronary syndrome (ACS) is a fatal entity and can be even more deadly if they develops concomitant complications in the form of arrhythmias like atrial fibrillation. Coronary artery disease is thought to be more severe in cases with ACS and atrial fibrillation. Objective: To determine the angiographic findings in patients presenting with acute coronary syndrome and atrial fibrillation and To find the involvement of more common circulation (right or left coronary circulation) leading to atrial fibrillation in acute coronary syndrome. Materials and Methods: This 6 month case series study conducted at department of Cardiology, Sheikh Zayed Hospital, Rahim Yar Khan from14-01-20 to 14-09-20. A total of 198 cases aged 30-60 years of both gender were included in the study through non-probability consecutive sampling. Patients suffering with ACS and has atrial fibrillation on presentation or develops within 24 hours of admission were included. They underwent coronary angiography to look for number of vessels involved, severity of coronary artery disease and culprit vessel involved. Results: In this study there were total 198 cases. Mean age of the participants was 50.09±5.88 years and mean duration of atrial fibrillation was 14.91± 4.51 hours. There were 70 (35.35%) cases with DM, 78 (39.39%) with HTN and 61 (30.81%) smokers. STEMI was found in 35 (17.68%) and NSTEMI in 152 (76.77%) of cases as in figure 05. One vessel disease was observed in 26 (13.13%), two vessel disease in 147 (74.24%) and three vessel disease in 25 (12.63%) of cases. Mild disease on angiography was seen in 45 (22.73%), moderate in 132 (66.67%) and severe in 21 (10.61%) of the cases.it was found that out of 198 patients , 146 ( 74 %) had right coronary artery culprit lesion and 51 ( 26 %) has left sided coronary circulation culprit lesion and from left coronary circulation, left circumflex was most commonly involved : 41 ( 21 % ) of patients as compared to only 10 ( 5 %) patients had culprit in left anterior descending artery. Conclusion: AF in patients with ACS is most commonly associated with right coronary artery lesionsand right type of coronary circulation. In terms of number and severity of disease the most common pattern observed was two vessel disease comprising almost 3/4th of all cases and moderate disease was in most of the vesselsrespectively. Key words: ACS, Atrial fibrillation

Objective: The aim behind this study was to scientifically assess the pattern of coronary artery disease in young males with acute coronary syndrome. Study Design: Prospective Observational study. Setting: Department of Cardiology, Isra University Hospital, Hyderabad. Period: March 2014 to February, 2019, Material & Methods: Data of 260 patients were enrolled who were males and having age less than 50 years and more than 25 years and presented with acute coronary syndrome. All the patients underwent coronary angiography for the assessment of pattern of coronary artery disease. Data were entered and analyzed by using Statistical Package for the Social Sciences version 21.0. Results: Out of total 260 patients, the mean age and SD of admitted patients was 42.21 ± 4.69 years and the age ranging between 33 to 50 years. The most common risk factors among young males who were admitted with ACS were cigarette smoking (39.61%, N = 103) and Hypertension (19.61%, N = 51) while least common was alcohol consumption (6.53%, N = 17). The most common pattern of CAD we have observed in our study was presence of three vessels coronary artery disease (25%, N = 65) and Branched Vessel Disease (23.07%, N = 60) while two Vessels CAD was least common (17.30%, N = 45). Conclusion: Our study shows that overall burden of coronary artery disease in males belongs to above 40 years of age residing at urban areas and belongs to middle socioeconomic background. The most common risk factor was cigarette smoking and the most common pattern of coronary artery disease was 3 vessel coronary artery disease and Branched Vessel Disease, respectively.

Abstract Objective Although the levels of plasma fibrinogen and albumin have been proven to be in relation to coronary heart disease (CHD), the association between fibrinogen-to-albumin ratio (FAR) and acute coronary syndrome (ACS) has not been adequately investigated. The aim of this study is to investigate the relationship between FAR and the presence and severity of CHD in patients with ACS. Methods and results A total of 1575 individuals who received coronary angiography (CAG) were enrolled. Patients were divided into the ACS group and the control group. The severity of ACS was determined by Gensini score, number of diseased coronary artery and the presence of myocardial infarction (MI). Data showed that the level of FAR in ACS group was higher than in the control group (81.20 ± 35.45 vs. 72.89 ± 20.24, P < 0.001). The results from subgroup analysis indicated that the values of FAR in the high Gensini score group, MI group and multiple-vessel stenosis group were higher than the matched subgroups. After adjustment for confounders, FAR was still independently related to the presence and severity of ACS (MI OR 2.097, 95%CI 1.430–3.076; High GS: OR 2.335, 95%CI 1.567–3.479; multiple-vessel disease: OR 2.088, 95%CI 1.439–3.030; P < 0.05). Conclusion The levels of FAR are independently associated with the presence and the severity of coronary artery disease in patients with ACS. Furthermore, FAR, as a more convenient and rapid biological indicator, may provide a new idea for predicting the presence and severity of ACS.
