Background: Type 2 diabetes mellitus (T2DM) is a prevalent and chronic metabolic disorder associated with an elevated risk of cardiovascular complications. This assessment aims to provide a comprehensive overview of the multifaceted factors contributing to cardiovascular risk in individuals with Type 2 diabetes. Aim and Objectives: The aim of this study was to assess cardiovascular risk in type 2 diabetic patients. Method: A prospective cohort study was conducted among known diabetes patients. Information on sociodemographic characteristics was gathered using a pre-tested semi-structured questionnaire, relevant lab investigations were performed, necessary clinical data was collected and the PROCAM score was used to calculate the risk of CVD. Results: 200 participants in the age range of 20-60 years took part in the study in total. Of them, women made up the majority (57%). Most of the participants belonged to the age group 41-60 years. About two-third of the patients (66.5%) had diabetes for a period of more than 5 years. With 17.5% of patients in PROCAM score category 6 and 13.5% of patients in category 7, nearly one-third (31%) of the patients were at high cardiovascular risk. Conclusion: Ultimately, a more nuanced comprehension of the cardiovascular risk factors in Type 2 diabetics can guide the development of targeted interventions and preventive strategies to improve patient outcomes and reduce the burden of cardiovascular morbidity and mortality in this high-risk population.
Globally, there is a rising incidence of diabetes mellitus. In 1985, 30 million persons worldwide were projected to have diabetes by the World Health Organization. It is estimated that by 2030, this number will have risen to at least 366 million, having reached 217 million in 2005[1]. People with diabetes mellitus are more susceptible to cardiovascular disease (CVD) and mortality than those without the condition, with a two- to four-fold increased risk of cardiovascular death [2]. Diabetes frequently coexists with other cardiovascular risk factors, which in turn accelerate the process of atherogenesis [3-6].
Diabetes mellitus is a chronic metabolic disorder characterized by elevated levels of blood glucose (hyperglycemia) resulting from defects in insulin secretion, insulin action, or both. Insulin, produced by the pancreas, is a hormone that regulates blood sugar by facilitating the uptake of glucose into cells. The clinical features for diabetes were Polyuria, Polydipsia, Polyphagia, Weight loss, Fatigue and Blurred vision. Microvascular complications include Retinopathy, Nephropathy, Neuropathy and macrovascular complications include Cardiovascular Disease, Peripheral Artery Disease (PAD). Lifestyle modifications such as healthy diet by focusing on balanced meals, controlling portion sizes, and monitoring carbohydrate intake; regular exercise as physical activity helps control blood sugar levels and improves overall health and weight management. Diabetes is a major risk factor for cardiovascular diseases (CVD). Individuals with diabetes have a higher likelihood of developing heart disease and stroke. Diabetes often coexists with high blood pressure (hypertension) and abnormal lipid profiles, further increasing the risk of CVD. Diabetes contributes to chronic inflammation and accelerates the formation of atherosclerotic plaques, narrowing blood vessels. Close monitoring of blood pressure, cholesterol levels, and blood glucose is crucial to managing cardiovascular risk. Lifestyle modifications and medications may be prescribed to reduce cardiovascular risk in individuals with diabetes.
Over the years, several risk scores have been created; however, only a small number of them have been especially designed with the diabetes community in mind. Twelve out of forty-five prediction models in a systematic assessment of models for predicting the risk of CVD in people with type 2 diabetes were created especially for these patients [7]. Most of them predicted the 5-year risk of either total or coronary heart disease (CHD), and the most often used predictors were age, sex, length of diabetes diagnosis, HbA1c (glycosylated haemoglobin A1c), and smoking. These models typically do not include non-traditional risk variables, like low birth weight and new biomarkers, which may have dubious clinical significance [8, 9]. Diabetes was one of several risk factors included in prediction models drawn from the general population, along with age, sex, systolic blood pressure, smoking, and cholesterol. Merely 33% of the risk scores have undergone external validation in a diabetic group [7].
The investigation involves the use of PROCAM Score in predicting cardiovascular events in T2DM patients. The PROCAM Score, which incorporates traditional risk factors such as age, gender, lipid profile, blood pressure, and smoking status, will be scrutinized for its applicability and predictive precision within this specific diabetic population.
The findings of this study aim to provide valuable insights into the utility of the PROCAM Score as a cardiovascular risk assessment tool specifically tailored for individuals with Type 2 diabetes. The implications of such assessments could contribute to more targeted and effective preventive strategies, ultimately reducing the burden of cardiovascular complications in this high-risk diabetic population

Established in 1978, the Prospective Cardiovascular Münster (PROCAM) study aimed to explore the epidemiology of coronary heart disease (CHD), developed in Northern Europe. Through the analysis of outcome data from a 10-year follow-up, a risk score for coronary events was developed, which included LDL cholesterol, HDL cholesterol,
systolic blood pressure, smoking, triglycerides, diabetes, family history of cardiovascular disease, sudden death and both fatal and non-fatal MI. Of great significance is the realization that the majority of these characteristics also represent components of the metabolic syndrome; low levels of HDL cholesterol and elevated triglycerides, the main ingredients of atherogenic dyslipidemia, which is frequently observed in patients with diabetes and/or metabolic syndrome, were identified as independent variables influencing coronary events. It takes into account various risk factors to assess the likelihood of a cardiovascular event. It may be noted that specific PROCAM score tables may vary, and it's crucial to use the version validated and recommended by healthcare professionals.
The risk factors considered in the PROCAM score:
1. Age
2. Gender
3. Total cholesterol
4. HDL cholesterol
5. Smoking status
6. Blood pressure
7. Family history of premature myocardial infarction (heart attack)
The actual PROCAM score calculation involves assigning points based on these factors and summing them to determine the overall risk. The risk is then categorized into different levels (e.g., low, moderate, high) (Table 1) [10].
In order to compare the levels of several risk factors in T2DM patients without CVD/stroke to those in T2DM patients with CVD/stroke and healthy individuals, the current study was carried out. Additionally, the study aimed to investigate the potential function of biomarkers in the primary prevention of CVDs and stroke.
The current study used the PROCAM score to examine the 10-year predicted cardiovascular risk and potential factors among individuals with diabetes mellitus. The purpose of this study was to evaluate the cardiovascular risk in patients with diabetes who were visiting a medical college hospital. Several common scoring systems are available for evaluating risk; PROCAM scoring was employed in this investigation. Study participants who were known to have diabetes were divided into three risk categories based on their scoring: low, middle, and high. According to this study, around 31% of participants have a high risk of cardiovascular problems. The results align with the research conducted by Marreswaran et al., [10] wherein 29.5% of study participants were at higher risk of CVD.
In 121 cities across 27 Indian states, a comparable multi-centric study [12] on newly diagnosed type 2 diabetes revealed a 7% greater risk of cardiovascular disease (CVD) among smokers and a 5% higher risk among hypertensive based on PROCAM scores. This is comparable to our present study indicating greater risk for smokers. According to this study, women are more likely to experience cardiovascular problems. It agrees with the results of the research conducted by Leon, Maddox, and Möller-Leimkühler [13, 14]. According to the previous study, women are three to five times more likely than men to acquire cardiovascular disease.
A study by Assmann G et al., [15] only five variables – age, sex, smoking, diabetes and systolic blood pressure – were included in the PROCAM cerebral ischemic risk score. This is consistent with data from the Atherosclerosis Risk in Communities study, which showed that the presence of elevated blood pressure and/or elevated fasting glucose were key components of the metabolic syndrome associated with increased risk of stroke.
Nearly half of the individuals in the current study (31%) had a high risk of hypertension; this is comparable to some studies that found that 60% of diabetics had hypertension. In another multi-center investigation [16], 42% of those with confirmed diabetes were found to have hypertension. The present study's findings are in line with previous research conducted by Corsi and Subramanian, indicating that individuals from higher socioeconomic classes which include smoking in India seem to have a higher likelihood of developing type 2 diabetes [17].
17.5% of all individuals used tobacco products, with a larger percentage among men. One of the main risk factors for CVD and the start of DM in this population is tobacco smoking. Smoking is taken into account as a significant factor in the PROCAM scores assessment. The Indian populace uses more chewing and smokeless tobacco than people in developed nations [18]. Research has demonstrated that smokeless tobacco is one of the factors contributing to insulin resistance and has higher nicotine content than cigarettes [19-22]. The public needs to be made aware of the dangers of consuming smokeless tobacco. According to this study, 54 % of participants are at high and intermediate risk of acquiring cardiovascular disease. This finding is consistent with a study by Garg et al. that found 51.9% of participants were at high risk of having the same condition using the Framingham risk score [23].
The evaluation of cardiovascular risk in patients with Type 2 Diabetes Mellitus (T2DM) is pivotal in addressing the heightened susceptibility to cardiovascular complications in this population. This study delved into multifaceted aspects, revealing a comprehensive landscape of factors contributing to increased cardiovascular risk in individuals with Type 2 diabetes. The research unequivocally demonstrated that individuals with Type 2 diabetes face a significantly elevated risk of cardiovascular events. Traditional risk factors, including age, gender, dyslipidemia, and hypertension, were identified as major contributors. The heightened cardiovascular risk observed in Type 2 diabetes patients necessitates a comprehensive and evolving approach to patient care. By unraveling the complexity of risk factors and acknowledging the dynamic nature of diabetes-related contributors, this study contributes to the evolving landscape of cardiovascular risk management in this high-risk population. Continued research and implementation of targeted interventions are essential for reducing the burden of cardiovascular morbidity and mortality in individuals with Type 2 diabetes.Top of Form
