Cardiovascular diseases (CVDs) stand as a significant global health challenge, responsible for a substantial burden of morbidity and mortality. These conditions, encompassing various heart and blood vessel disorders, include coronary artery disease, heart failure, stroke and hypertension, among others. In India, CVDs are a leading cause of death and disability and Himachal Pradesh, with its serene landscapes and unique geographical challenges, is not immune to this health crisis. Understanding the awareness and knowledge levels of CVD risk factors and prevention strategies among the residents of District Shimla in Himachal Pradesh is paramount for effective public health interventions [1-3].

CVDs often manifest silently, progressing stealthily until severe complications arise. Yet, a significant proportion of CVDs can be prevented through lifestyle modifications and early intervention. Lifestyle factors, such as tobacco use, unhealthy diets, physical inactivity and excessive alcohol consumption, along with medical risk factors like hypertension, diabetes and obesity, contribute to the development of CVD. Therefore, raising awareness about these risk factors and promoting preventive measures is crucial [4,5].

The objective of this study is to gauge the levels of awareness and knowledge regarding risk factors and prevention strategies related to cardiovascular disease among the general population of District Shimla, Himachal Pradesh. By assessing the current understanding of CVD risk factors, lifestyle choices and preventive measures, this research aims to identify gaps in knowledge that can inform targeted awareness campaigns, healthcare policies and community-based interventions.

The unique topography and demographics of Shimla District may present specific challenges and opportunities for addressing CVD. Factors like altitude, dietary habits and cultural practices can influence the prevalence and management of CVD risk factors. Therefore, tailoring interventions to the distinct needs of this region is essential for effective disease prevention.

In addition to individual-level awareness, community-level initiatives, such as promoting heart-healthy environments and encouraging regular health check-ups,  play a vital  role in reducing CVD burden.

Ultimately, the objective of this study is to equip the residents of District Shimla with the knowledge and tools necessary to make informed choices about their heart health, ultimately leading to a healthier and more vibrant community.

Cardiovascular Diseases (CVDs) remain a significant global health challenge and understanding the awareness and knowledge levels regarding CVD risk factors and prevention strategies is essential for effective public health interventions. This discussion section will delve into the findings of the study conducted in District Shimla, Himachal Pradesh and compare them with existing literature to identify knowledge gaps and opportunities for improving cardiovascular health awareness.

In this study, 69.5% of respondents could name some common cardiovascular diseases that affect the heart and blood vessels. This level of awareness is notable, as recognizing CVDs is the first step in understanding the associated risks and prevention strategies. However, further research could explore participants' knowledge of less common CVDs to assess the comprehensiveness of their awareness.

Approximately 66.75% of participants were aware of the major risk factors associated with cardiovascular diseases. These risk factors include tobacco use, high blood pressure, unhealthy diets, physical inactivity, excessive alcohol consumption and diabetes. This finding suggests a relatively good understanding of the fundamental risk factors contributing to CVD. Nevertheless, it is essential to examine whether individuals are aware of lesser-known risk factors and their impact on heart health.

Awareness of the link between smoking or tobacco use and heart health was relatively high, with 66% of respondents acknowledging this connection. This finding is encouraging, considering the severe impact of tobacco on cardiovascular health. Approximately 66.25% of participants reported engaging in physical activity or exercise as part of their routine. While this suggests a significant portion of the population prioritizes physical activity, further research could explore the intensity and frequency of these activities to determine whether they meet recommended guidelines for heart health.

Approximately 59.75% of respondents were familiar with the term "cholesterol" and its role in heart health. Understanding cholesterol and its impact on CVD risk is crucial, as it can influence dietary choices and lifestyle decisions. Approximately 64.25% of participants were aware of the importance of a balanced diet in preventing heart diseases. This awareness indicates the potential for dietary improvements to reduce CVD risk.
