Introduction & Background
Cardiovascular diseases (CVDs) pose a significant global burden in terms of morbidity, mortality, and economic impact. CVDs are highly prevalent worldwide [1]. According to the World Health Organization (WHO), CVDs are the leading cause of death globally, accounting for approximately 17.9 million deaths in 2019, representing 32% of all global deaths [2]. Moreover, CVDs affect individuals across all regions, countries, and socio-economic groups. They contribute to a substantial number of deaths each year [1]. Ischemic heart disease and stroke are the most common types of CVDs causing mortality. Low- and middle-income countries are particularly affected by the burden of CVD-related deaths [3]. Several risk factors contribute to the development of CVDs. These include hypertension, dyslipidemia, smoking, obesity, diabetes, physical inactivity, unhealthy diet, excessive alcohol consumption, and psychosocial factors such as stress [4]. The presence of multiple risk factors further amplifies the risk of developing CVDs. They also impose a substantial economic burden on healthcare systems and societies.
Lifestyle modifications serve as crucial preventive measures for CVDs. Risk factors associated with CVDs are modifiable and can be influenced through lifestyle modifications. Lifestyle modifications, such as adopting a healthy diet, engaging in regular physical activity, quitting smoking, managing stress, and maintaining a healthy weight, directly target these risk factors. By addressing modifiable risk factors, individuals can significantly reduce their risk of developing CVDs [5]. Lifestyle modifications offer a comprehensive approach to CVD prevention. Unlike pharmaceutical interventions that target specific pathways or risk factors, lifestyle modifications impact multiple risk factors simultaneously. Lifestyle modifications provide long-term benefits for cardiovascular health. By adopting healthy habits early in life and maintaining them over time, individuals can significantly reduce their risk of developing CVDs in the future. These modifications have a cumulative effect on cardiovascular health, resulting in sustained improvements and a lower risk of adverse events over time [6]. Lifestyle modifications complement medical interventions for CVDs. In many cases, lifestyle modifications can reduce the reliance on medications or enhance their effectiveness. For individuals already diagnosed with CVDs, lifestyle modifications serve as essential components of disease management, improving outcomes and quality of life
Cardiovascular diseases (CVDs) remain a leading cause of morbidity and mortality worldwide. Lifestyle modifications have gained increasing recognition as key interventions in preventing and managing CVDs. This narrative review aims to provide a thorough assessment of the impact of lifestyle modifications on cardiovascular health. The review encompasses various aspects, including diet, physical activity, smoking cessation, stress management, and weight management. Additionally, the review explores the underlying mechanisms by which lifestyle modifications influence cardiovascular health and highlights the evidence from clinical trials, observational studies, and meta-analyses. The findings of this review emphasize the importance of lifestyle modifications in reducing the risk factors associated with CVDs and improving cardiovascular outcomes.

Impact of diet on cardiovascular health
Role of a Heart-Healthy Diet in Reducing Cardiovascular Risk
A heart-healthy diet plays a critical role in reducing cardiovascular risk. A heart-healthy diet helps lower levels of low-density lipoprotein (LDL). High LDL is a major risk factor for the development of atherosclerosis. By reducing dietary intake of saturated and trans fats, a heart-healthy diet can help maintain optimal cholesterol levels and prevent the formation of plaque [7]. A heart-healthy diet promotes the control of blood pressure, another significant risk factor for CVDs. A diet rich in fruits, vegetables, whole grains, and low-fat dairy products, known as the Dietary Approaches to Stop Hypertension (DASH) diet, has been shown to effectively lower blood pressure. It emphasizes the consumption of foods that are low in sodium, high in potassium, magnesium, and calcium, which collectively contribute to maintaining healthy blood pressure levels [8]. Chronic inflammation plays a crucial role in the development and progression of CVDs. A heart-healthy diet, particularly one that includes anti-inflammatory foods, can help reduce inflammation in the body. Foods such as fatty fish (rich in omega-3 fatty acids), nuts, seeds, whole grains, fruits, and vegetables possess anti-inflammatory properties. By incorporating these foods into the diet, inflammation markers can be reduced, promoting cardiovascular health [9].
Maintaining a healthy weight is essential for reducing cardiovascular risk. A heart-healthy diet focuses on nutrient-dense foods that are lower in calories, unhealthy fats, and added sugars. It emphasizes portion control and encourages the consumption of lean proteins, fiber-rich foods, and healthy fats. Such dietary patterns, combined with regular physical activity, promote weight management and help prevent obesity, a significant risk factor for CVDs [10]. The long-term benefits include adopting a heart-healthy diet and making it lifelong to have sustained benefits for cardiovascular health. Consistently following a heart-healthy diet can help prevent the development of CVDs, reduce the risk of heart attacks, strokes, and other cardiac events, and contribute to overall longevity and well-being
