Grid Search for Predicting Coronary Heart Disease by Tuning Hyper-Parameters

Diagnosing the cardiovascular disease is one of the biggest medical difficulties in recent years.Coronary cardiovascular(CHD)is a kind of heart and blood vascular disease.Predicting this sort of cardiac illness leads to more precise decisions for cardiac disorders.Implementing Grid Search Optimization(GSO)machine training models is therefore a useful way to forecast the sickness as soon as possible.The state-of-the-art work is the tuning of the hyperparameter together with the selection of the feature by utilizing the model search to minimize the false-negative rate.Three models with a cross-validation approach do the required task.Feature Selection based on the use of statistical and correlation matrices for multivariate analysis.For Random Search and Grid Search models,extensive comparison findings are produced utilizing retrieval,F1 score,and precision measurements.The models are evaluated using the metrics and kappa statistics that illustrate the three models’comparability.The study effort focuses on optimizing function selection,tweaking hyperparameters to improve model accuracy and the prediction of heart disease by examining Framingham datasets using random forestry classification.Tuning the hyperparameter in the model of grid search thus decreases the erroneous rate achieves global optimization.

Risk Assessment and Risk Perception of Coronary Heart Disease in Gaza Strip, Palastine

Aim: The aim of the present study was to estimate the prevalence of coronary heart diseases (CHD) risk factors among Ghaza (Palastine) university students, to assess the CHD risk among them using a suitable scoring system and to identify how they perceive their risk of CHD. Methods: During the period from May 2008 to May 2009, 501 students were involved. Participants were subjected to the following activities;self administered questionnaire: including socio-demographic data, medical history of chronic diseases, family history about CHD, knowledge and perception of risk factors, anthropometric measurements in addition to laboratory testing. Results: The mean age was 20.8 ± 2.07 years;54% were females. The prevalence of hypertension and DM was 3.6% and 0.4% while it was 2.6% for hypercholesterolemia. The mean levels of LDL-C (88 mg/dl vs 85.5 mg/dl) and HDL-C (52.4 mg/dl vs 42.6 mg/dl) were higher among females than among males. Smoking was more prevalent among males than among females (33.1% vs 1.7%) with a total prevalence of 19%. Overweight and obesity were more prevalent among males (30.7% vs 22.5% and 9.6% vs 5.6%). In contrast to risk perception female students tend to be more knowledgeable than males with regards to different aspects of CHD. The overall level of perceived risk was moderate. Logistic regression analysis revealed that age and sex were associated significantly by higher level of total perception (p < 0.05). Conclusion: Health education and health promotion programs should be implemented and integrated within the primary health care sectors and directed to university students before admission. Further research needed to be implemented on larger sample to test knowledge and perception of the public in regard to their risk for heart disease including school children and community so that education could be provided in a more focused manner.

Lipid Profile of Coronary Heart Disease Patients: A Prospective Observational Study

Background: Coronary heart disease (CHD) remains the major cause of mortality and morbidity in the entire world population despite therapeutic advances that control many risk factors. Lipid profile is regarded as an important factor in the development of coronary heart disease. There have been numerous studies confirming the association of hyperlipidemias with coronary heart disease in most of the Western as well as Asian countries of the world. But we have very little data on the relation between CHD and lipid profile. Aim of the Study: The aim of this study was to assess abnormal lipid levels and their association with coronary heart disease. Methods: This comparative observational study was conducted at the Department of Cardiology in M. Abdur Rahim Medical College, Dinajpur, Bangladesh from January 2019 to December 2019. Properly written consent was taken from all the participants before starting the main part of the investigation. Obeying inclusion and exclusion criteria of the study, a total of 131 participants were finalized as the study population. Among them, the Case Group was formed with 90 patients who had CHD, and with 41 healthy people, the Control Group was formed. All necessary data were collected, analyzed, and disseminated by several programs of MS-Office and SPSS version 23. Result: The study was conducted with 90 case group participants and 41 control group participants. Among the case group, 78% were male and 22% were female. Among the male case group participants, 44.29% were from 51 - 60 years of age, 35.71% were from 41 - 50 years of age and the rest 20% were above 60 years of age. On the other hand, among the female participants of Case Group, 45% were from 51 - 60 years of age, 30% from 41 - 50 years of age, and 25% were over 60 years of age. Regression analysis between the male and the female showed the P-value of 0.242. Serum cholesterol concentration and HDL concentration were significant between the Case and Control groups in all age groups and the P-value was <0.0001 in every age group. Triglyceride concentration was significant between the Case and Control groups in 41 - 50 and 51 - 60 years age groups with a P-value of <0.0001. But in the >60 years age group, we did not find any significant correlation and there the P-value was 0.478. LDL concentration between the groups showed significant correlations between the Case and Control groups in 41 - 50 and 51 - 60-years’ age groups where the P values were found, <0.0001 and 0.0002 respectively. But in the >60 years’ age group, we did not find any significant correlation and there the P- value was 0.515. Conclusion: In this study, it was found that the total cholesterol, triglycerides, HDL cholesterol, and LDL cholesterol concentrations were significantly higher in coronary heart disease (CHD) patients.

Pulse Wave Analysis in Patients with Coronary Heart Disease Based on Hilbert-Huang Transformation and Time-domain

Objective: To study the characteristics of pulse tracings in CHD, and objectively evaluate the significance of pulse signal in diagnosis and appreciation of therapeutic effect in patients with coronary heart disease(CHD), and accordingly provide with theoretic proofs for developing non-invasive technique of pulse diagnosis. Methods: By using the pulse detection system, pulse graphs in CHD patients, patients without CHD and "health" adults were collected and compared. Then characters of the pulse signal were analyzed with Hilbert-Huang transformation routine (HHT) and time-domain method respectively. Results: There existed characteristic change in pulse graph in CHD. ① h1,h3,h4,h3/h1,t,t5/t4 in time domain parameters of pulse graph increased and w1 was widened. ② 44% of C2 wave in HHT display showed chaotic and disorderly wave and irregularly wave amplitude in CHD. And 72% of C5 Wave exhibited in irregular wave with average wave amplitude over 10 gram-forces. These changes were significantly different from health adults. Conclusion: Characteristic wave of pulse graph extracted with methods of time domain or HHT routine might be considered as proofs for diagnosis and differentiation in CHD. Our researches prognosticate that pulse diagnosis can be used as an ancillary determination in occurrence of CHD for reasons of the advantage of convenient operation and non-invasion.

Reducing cholesterol to prevent coronary heart disease

Coronary heart disease (CHD) remains the number one killer of men and women in the United States of America despite major advances in interventional technologies for the treatment of coronary artery disease. CHD is rapidly becoming a major cause of morbidity and mortality in developing nations as well and is now recognized as the leading cause of death worldwide.

Depression as a risk factor for coronary heart disease—How strong is the evidence?

A critical appraisal is made of the evidence that depression is a causal risk factor for coronary heart disease. PubMed and Science Citation Index were searched for relevant papers. Forty eight papers satisfying inclusion criteria and reporting an association between a measure of depression and a coronary disease outcome were compared in terms of baseline assessment, exposure and endpoint definition, covariates measured and whether changes in, or treatment of, depression was assessed during follow-up. There was considerable variation in the definition of depression and coronary heart disease and contradictory findings are reported. Conventional risk factors for coronary heart disease were not assessed consistently or adequately. Only three of the forty-eight papers gave consideration to the time course of depression during follow-up and prior to study entry. Potentially confounding variables such as anxiety, personality traits and other psychiatric disorders were not taken into consideration in the majority of papers. Treatment of depression during the follow-up period was not mentioned in any of the papers. In light of identified methodological shortcomings and the inconsistent findings reported we suggest that there is as yet no convincing evidence that depression is an independent causal risk factor for coronary heart disease.

Hyperhomoysteinemia as a risk factor for coronary heart diseases in chronic hepatitis C patients

Hepatitis C virus is one of the major health problems worldwide. It affects mainly the liver but several extrahepatic manifestations are also accounted. Chronic hepatitis C patients are at an increased risk of developing hepatic steatosis, which share many clinical features with the metabolic syndrome. Hepatic steatosis has also been associated with elevated levels of markers of inflammation such as homocysteine, identified as hyperhomocysteinemia (HHC). HHC due to Methylenetetrahydrofolate Reductase (MTHFR) gene, in particular the C677T polymorphism, was recently associated with coronary heart diseases (CHD) in chronic hepatitis C (CHC) patients. Homocysteine is an intermediate in methionine metabolism, which takes place mainly in the liver metabolism. Deficiencies of micronutrients (folate, vitamin B 6 and possibly vitamin B 12) along with mild hyperhomocysteinemia, perhaps, act synergistically with other classical risk factors to further increase the risk of CHD. Clinical data indicate that HHC is associated with an increased incidence of CHD as well as with the severity of the disease in CHC patients. In conclusion, HHC might be a potential aetiological factor of CHD in CHC patients. The aim of this review is to investigate the progression of coronary heart diseases in chronic hepatitis C patients and correlate with levels of homocysteine in concurrence to genetic defects and nutrient deficiencies. However, future studies need to clarify the mechanistic role of HHC in CHD and CHC as a useful paradigm with most interesting therapeutic implications.

Clinical perspective on C-reactive protein in prognostication of major adverse cardiac events in the elderly with established coronary heart disease

The systemic response to tissue injury, regardless of cause is characterized by a cytokine-mediated alteration in the hepatic synthesis of a number of different plasma proteins,known collectively as 'acute phase reactants'. These proteins include C-reactive protein, serum amyloid A protein, alphal glycoprotein, ceruloplasmin, alpha macroglobulins, complement components (C1-C4, factor B, C9, C11), alpha1antitrypsin, alpha1 antichymotrypsin, fibrinogen, prothrombin,factor Ⅷ, plasminogen, haptoglobin, ferritin, immunoglobulins and lipoproteins. The initiation of the acute phase response is linked to the production of hormone-like polypeptide mediators now called cytokines, namedly, interleukin 1(IL-1),tumor necrosis factor, interferon gamma, interleukin 6 (IL-6),leukemia inhibitory factor, ciliary neurotropic factor, oncostatin M, and interleukin 11 (IL- 11).……

Study on the relationship between Lp-PLA2, D- dimer and Galectin-3 and atherosclerotic vulnerable plaque in patients with coronary heart disease

Objective: To explore the relationship and clinical value of serum phospholipase A2 (Lp-PLA2), d-dimers, and serum galectin-3 (galectin-3) with atherosclerotic vulnerable plaques in coronary artery patients with coronary heart disease. Methods: A total of 248 patients who underwent coronary angiography (CAG) and intravascular ultrasound (IVUS) in our hospital from June 2017 to September 2018 were selected and divided into vulnerable plaque group (89), stable plaque group (89) and control group (70) according to the examination results. The serum levels of Lp-PLA2, d-dimer and galectin-3 in three groups were compared, as well as their correlation with the detection parameters. To evaluate the clinical value of Lp-PLA2, d-dimer and galectin-3 in patients with coronary heart disease (CHD) with atherosclerotic vulnerable plaque. Results: Serum Lp-PLA2, d-dimer and galectin-3 levels were significantly different from the three groups (P<0.05), and the control group < stable plaque group <vulnerable plaque group (P<0.05). Correlation analysis showed that Lp-PLA2, d-dimer and galectin-3 were significantly positively correlated with plaque area, plaque load, necrotic core and calcified tissue (P<0.01), and negatively correlated with fibrous lipid and fibrous tissue (P<0.01). ROC curve showed that Lp-PLA2, d-dimer and galectin-3 had certain predictive value for vulnerable coronary atherosclerotic plaques (AUC=0.939, 0.977, 0.920, P<0.01), and the three combinations (AUC=0.986, P<0.01) had higher predictive value. Conclusion: Serum Lp-PLA2, d-dimer and galectin-3 are significantly correlated with coronary atherosclerotic vulnerable plaques in patients with coronary heart disease, with high sensitivity and specificity, which can be used for the diagnosis and treatment of early atherosclerotic vulnerable plaques.
