Background: Hypertension (HTN) is one of the leading contributors to the global burden of diseases. Elevated blood pressure affects more than one billion individuals and causes an estimated 9.4 million deaths per year. Assessing hypertension knowledge, attitude and practice (KAP) is crucial for management of HTN. This study aimed to assess the KAP of hypertensive patients about factors affecting blood pressure. Methods: A cross sectional study was carried out in patients attending the out patient department in a tertiary care hospital. The study was conducted for a period of 2 months. A questionnaire was prepared in accordance with the literature to measure the knowledge attitude and practices about hypertension in general population of Kashmir, India. Results: 58.65% (305) of the participants demonstrated a commendable level of knowledge regarding hypertension. Additionally, 41.73% and 39.23% of participants in this category exhibited positive practices and attitudes respectively. The statistically significant p-value of 0.05 suggests that there may be a relationship between excellent knowledge and positive practices and attitudes among hypertensive patients. Conclusion: This study reveals a significant association between the levels of knowledge, attitude and practices among hypertensive patients. Participants with excellent knowledge exhibited more positive practices and attitude, as indicated by the lower p-value of 0.05.
