INTRODUCTION
The COVID-19 pandemic has brought to light numerous challenges in healthcare, ranging from immediate clinical management to long-term health consequences. Among these challenges, the intricate relationship between hyperglycemia and cardiovascular disease (CVD) has garnered significant attention. Hyperglycemia, characterized by elevated blood glucose levels, has long been recognized as a risk factor for CVD [1]. However, the emergence of COVID-19 has added a new layer of complexity to this association. The renin-angiotensin-aldosterone system (RAAS) plays a crucial role in regulating blood pressure and fluid balance in the body. In the context of diabetes and the aftermath of the COVID-19 pandemic, understanding the physiopathology of cardiovascular diseases (CVD) is important. RAAS is a hormone system that regulates blood pressure and fluid balance. Renin is released by the kidneys in response to low blood pressure or low sodium levels, leading to the conversion of angiotensinogen to angiotensin I.ACE converts angiotensin I to angiotensin II, a potent vasoconstrictor [2]. Angiotensin II is involved in vasoconstriction, sodium retention, and the release of aldosterone. Aldosterone, stimulated by angiotensin II, promotes sodium and water retention in the kidneys. Increased aldosterone levels can contribute to volume overload and elevated blood pressure. In diabetes, there is often dysregulation of the RAAS, with an overactivation of angiotensin II. Chronic hyperglycemia can contribute to endothelial dysfunction, oxidative stress, and inflammation. Elevated angiotensin II levels in diabetes contribute to endothelial dysfunction, impairing the normal function of blood vessels. Endothelial dysfunction is a key factor in the development of atherosclerosis, a common pathology in CVD. Atherosclerosis involves the buildup of plaques in arterial walls, leading to reduced blood flow. Diabetes increases the risk of atherosclerosis, and individuals with diabetes are at higher risk for CVD, including coronary artery disease and peripheral arterial disease. Activation of the RAAS can contribute to hypertension in individuals with diabetes. Hypertension is a major risk factor for CVD, including heart attacks and strokes.COVID-19 has been associated with cardiovascular complications, including inflammation, endothelial dysfunction, and thrombosis. Individuals with diabetes may face an increased risk of severe outcomes due to the combination of diabetes-related vascular complications and the impact of COVID-19 on the cardiovascular system. Medications that target the RAAS, such as ACE inhibitors or angiotensin receptor blockers (ARBs), are commonly used to manage hypertension and cardiovascular risk in individuals with diabetes. Comprehensive management of diabetes, including glycemic control, blood pressure management, and lifestyle modifications, is essential to reduce the risk of CVD. Understanding the interplay between RAAS, diabetes, and COVID-19 is crucial for developing effective strategies to manage cardiovascular risk in individuals with diabetes, particularly in the post-COVID-19 era. Regular monitoring and collaboration with healthcare providers are important for optimizing cardiovascular health in this population.
This introduction sets the stage by outlining the significance of hyperglycemia as a risk factor for CVD and the impact of COVID-19 on exacerbating this risk. It highlights the need for a deeper understanding of the mechanisms underlying the hyperglycemia-CVD association in the post-COVID-19 era and emphasizes the importance of proactive management strategies to mitigate cardiovascular risk in individuals with hyperglycemia. Through this commentary, we aim to provide insights into effective approaches for healthcare providers to navigate the evolving landscape of hyperglycemia-related CVD in the aftermath of the COVID-19 pandemic [3].

Hyperglycemia: A Risk Factor for Cardiovascular Disease
Hyperglycemia, characterized by elevated levels of blood glucose, stands as a well-established risk factor for cardiovascular disease (CVD). This section of the commentary delves into the intricate relationship between hyperglycemia and CVD, elucidating the mechanisms through which hyperglycemia contributes to cardiovascular risk.
Pathophysiological Mechanisms: Hyperglycemia exerts deleterious effects on multiple pathways implicated in the development and progression of CVD. These include oxidative stress, inflammation, endothelial dysfunction, and dyslipidemia, all of which contribute to the initiation and progression of atherosclerosis, the underlying pathology of most CVD [5].
Endothelial Dysfunction: Elevated glucose levels impair endothelial function, leading to reduced nitric oxide bioavailability, increased vascular permeability, and enhanced expression of adhesion molecules. These alterations promote a pro-inflammatory and pro-thrombotic vascular milieu, fostering the development of atherosclerosis and predisposing individuals to CVD events.
Oxidative Stress: Hyperglycemia-induced oxidative stress plays a pivotal role in vascular damage and atherosclerosis. Excessive production of reactive oxygen species (ROS) overwhelms endogenous antioxidant defenses, leading to endothelial dysfunction, lipid peroxidation, and vascular inflammation, all of which contribute to CVD pathogenesis.
Inflammation: Chronic low-grade inflammation is a hallmark of both hyperglycemia and CVD. Elevated glucose levels activate inflammatory signaling pathways and cytokine production, perpetuating a state of systemic inflammation that promotes atherosclerosis and plaque instability, ultimately increasing the risk of cardiovascular events.
Dyslipidemia: Hyperglycemia disrupts lipid metabolism, resulting in dyslipidemia characterized by elevated triglycerides, decreased high-density lipoprotein (HDL) cholesterol, and altered lipoprotein particle size and composition. These lipid abnormalities contribute to the development of atherosclerosis and predispose individuals to CVD.
Hyperglycemia as a Central Player: Beyond these specific mechanisms, hyperglycemia acts as a central player in the pathogenesis of CVD by exacerbating other traditional risk factors such as hypertension, obesity, and insulin resistance, thereby amplifying cardiovascular risk [6].
Impact of COVID-19 on Hyperglycemia and Cardiovascular Health
The COVID-19 pandemic has brought about profound disruptions to healthcare systems worldwide, with significant implications for both hyperglycemia management and cardiovascular health. This section of the commentary explores the multifaceted impact of COVID-19 on hyperglycemia and cardiovascular health, shedding light on the interplay between the viral infection and these interconnected conditions.
Exacerbation of Hyperglycemia: COVID-19 infection poses a unique challenge for individuals with pre-existing hyperglycemia or diabetes. Studies have revealed that COVID-19 can exacerbate hyperglycemia through various mechanisms, including increased insulin resistance, β-cell dysfunction, systemic inflammation, and stress-induced hyperglycemia. The resultant hyperglycemia not only complicates the management of COVID-19 but also heightens the risk of adverse outcomes, including cardiovascular complications [7].
Direct Cardiovascular Effects of COVID-19: Beyond its impact on hyperglycemia, COVID-19 directly affects cardiovascular health. The virus can lead to myocardial injury, myocarditis, arrhythmias, thromboembolic events, and exacerbation of underlying CVD. Individuals with hyperglycemia are particularly vulnerable to these cardiovascular complications, given their heightened cardiovascular risk profile.
Indirect Effects on Cardiovascular Health: The indirect effects of COVID-19, such as disruptions to healthcare delivery, delayed access to medical care, changes in lifestyle behaviors, and psychological stress, can further exacerbate cardiovascular risk factors and compromise cardiovascular health. Individuals with hyperglycemia may face additional challenges in managing their condition effectively amidst the upheaval caused by the pandemic.
Implications for Long-Term Cardiovascular Risk: The long-term consequences of COVID-19 on cardiovascular health remain a topic of active investigation. Emerging evidence suggests that individuals recovering from severe COVID-19 may experience persistent cardiovascular sequelae, including endothelial dysfunction, myocardial fibrosis, and accelerated atherosclerosis, which could predispose them to future CVD events.
Need for Integrated Care: Given the intertwined nature of hyperglycemia, COVID-19, and cardiovascular health, a holistic and integrated approach to care is imperative. Healthcare providers must prioritize comprehensive management strategies that address both hyperglycemia and cardiovascular risk factors, ensuring optimal outcomes for individuals affected by COVID-19 [8].
Mechanisms Underlying the Hyperglycemia-CVD Association
Understanding the mechanisms underlying the association between hyperglycemia and cardiovascular disease (CVD) is essential for elucidating the pathophysiology of CVD in individuals with elevated blood glucose levels. This section of the commentary explores the intricate mechanisms through which hyperglycemia contributes to the development and progression of CVD [9].
Oxidative Stress and Endothelial Dysfunction: Hyperglycemia induces oxidative stress by promoting the production of reactive oxygen species (ROS) and impairing antioxidant defense mechanisms. This oxidative stress leads to endothelial dysfunction, characterized by reduced nitric oxide bioavailability, increased expression of adhesion molecules, and enhanced vascular permeability. Endothelial dysfunction plays a central role in the initiation and progression of atherosclerosis, the underlying pathology of most CVD.
Inflammation: Chronic low-grade inflammation is a hallmark of both hyperglycemia and CVD. Elevated glucose levels activate inflammatory signaling pathways and stimulate the production of pro-inflammatory cytokines and chemokines. This systemic inflammation contributes to the development of atherosclerosis by promoting endothelial activation, leukocyte recruitment, foam cell formation, and plaque destabilization [10].
Advanced Glycation End Products (AGEs): Hyperglycemia promotes the non-enzymatic glycation of proteins, lipids, and nucleic acids, leading to the formation of advanced glycation end products (AGEs). AGEs interact with specific receptors, such as the receptor for AGEs (RAGE), triggering oxidative stress, inflammation, and endothelial dysfunction. Accumulation of AGEs in vascular tissues contributes to arterial stiffness, impaired vasodilation, and accelerated atherosclerosis.
Dyslipidemia and Lipotoxicity: Hyperglycemia disrupts lipid metabolism, leading to dyslipidemia characterized by elevated triglycerides, reduced high-density lipoprotein (HDL) cholesterol, and altered lipoprotein particle size and composition. These lipid abnormalities promote the accumulation of lipid-laden foam cells within arterial walls, fostering the development of atherosclerotic plaques. Additionally, excess circulating lipids can induce lipotoxicity in cardiomyocytes and vascular cells, further exacerbating cardiovascular risk.
Insulin Resistance and Hyperinsulinemia: Hyperglycemia is often accompanied by insulin resistance and compensatory hyperinsulinemia. Insulin resistance impairs insulin signaling pathways in target tissues, including the vasculature, promoting endothelial dysfunction, inflammation, and dyslipidemia. Hyperinsulinemia exerts direct pro-atherogenic effects by stimulating vascular smooth muscle cell proliferation and increasing the production of pro-inflammatory cytokines [11].
Strategies for Early Detection of Hyperglycemia and Cardiovascular Risk
Early detection of hyperglycemia and cardiovascular risk is crucial for timely intervention and effective management to prevent or delay the onset of cardiovascular disease (CVD). Table-1 outlines strategies for identifying individuals at risk of hyperglycemia and CVD, enabling proactive measures to mitigate cardiovascular risk.

Pharmacological Interventions
Pharmacological interventions are integral components of hyperglycemia management, particularly when lifestyle modifications alone are insufficient to achieve glycemic targets. In the post-COVID-19 era, selecting appropriate pharmacotherapy requires consideration of individual patient characteristics, comorbidities, medication adherence, and potential drug interactions. This section outlines key pharmacological interventions for hyperglycemia management:
Metformin: Metformin is considered first-line therapy for the treatment of type 2 diabetes due to its efficacy, safety profile, and cardiovascular benefits. It improves insulin sensitivity, reduces hepatic glucose production, and modestly lowers blood glucose levels without causing hypoglycemia or weight gain. Metformin is often prescribed as initial monotherapy or in combination with other antidiabetic agents [19].
Sulfonylureas: Sulfonylureas stimulate insulin secretion from pancreatic beta cells and are commonly used as adjunctive therapy in individuals with type 2 diabetes who fail to achieve glycemic control with metformin alone. Examples include glibenclamide, gliclazide, and glimepiride. Sulfonylureas can cause hypoglycemia and weight gain, limiting their use in certain patient populations.
Insulin Therapy: Insulin therapy is indicated for individuals with type 1 diabetes and often required for those with type 2 diabetes who have advanced disease or inadequate glycemic control despite oral agents. Various insulin formulations are available, including rapid-acting, short-acting, intermediate-acting, and long-acting insulin analogs. Insulin therapy can be administered via multiple daily injections or continuous subcutaneous infusion (insulin pump).
GLP-1 Receptor Agonists: GLP-1 receptor agonists mimic the effects of endogenous glucagon-like peptide-1 (GLP-1), enhancing insulin secretion, suppressing glucagon secretion, slowing gastric emptying, and promoting satiety. These agents, such as exenatide, liraglutide, and dulaglutide, are injectable medications used as adjunctive therapy in type 2 diabetes management. GLP-1 receptor agonists are associated with weight loss, cardiovascular benefits, and reduced risk of hypoglycemia [20].
DPP-4 Inhibitors: Dipeptidyl peptidase-4 (DPP-4) inhibitors enhance endogenous GLP-1 levels by inhibiting their degradation, thereby improving glycemic control. Examples include sitagliptin, saxagliptin, and linagliptin. DPP-4 inhibitors are oral agents commonly used as monotherapy or in combination with other antidiabetic medications. They are generally well-tolerated and have a low risk of hypoglycemia.
SGLT2 Inhibitors: Sodium-glucose cotransporter-2 (SGLT2) inhibitors block glucose reabsorption in the proximal renal tubules, leading to increased urinary glucose excretion and lower blood glucose levels. Empagliflozin, canagliflozin, and dapagliflozin are examples of SGLT2 inhibitors used in type 2 diabetes management. These agents offer cardiovascular and renal benefits, including reductions in heart failure hospitalization and progression of chronic kidney disease [21].
Combination Therapy: Combination therapy with two or more antidiabetic agents with complementary mechanisms of action is often required to achieve glycemic targets and address multiple pathophysiological defects in hyperglycemia. Fixed-dose combinations of oral agents or injectable medications are available to simplify treatment regimens and improve medication adherence [22].
Individualizing pharmacological therapy based on patient-specific factors, monitoring treatment response, and adjusting therapy as needed are essential principles of hyperglycemia management in the post-COVID-19 era. Healthcare providers should strive to optimize glycemic control while minimizing the risk of hypoglycemia, weight gain, and adverse cardiovascular outcomes, ultimately improving patient outcomes and quality of life [23].
Monitoring and Follow-up
Monitoring and follow-up are integral components of hyperglycemia management, ensuring that treatment goals are achieved, and adjustments are made as needed to optimize patient outcomes. In the post-COVID-19 era, a proactive approach to monitoring and follow-up is essential to mitigate cardiovascular risk and address the evolving healthcare landscape.
