Increase in heart rate tend to increase work loadof heart and it could worsen condition in people with diseased heart.Methods: This was nonrandomized prospective open labeled parallelgroups study carried out at MIMC. The sample size of the study wasbased on 128 subjects (62 Ovaltine and 66 Coffee) and same numberof controls for Ovaltine and Coffee respectively in a cross over asnegative control. The study was based on 4 groups A, B, C and D wereCoffee control, Coffee, Ovaltine control and Ovaltine respectively.Subjects with history of heart diseases, medication effecting heart rateand anxiety disorders were excluded from the study. The unwanted effects were noted duringthe study. Results: The increase in mean heart rate of Coffee and Ovaltine groups were 5.48(6.76%) p value 0.003 and 5.29 (6.75%) p value 0.02 respectively. The increase in meanheart rate of Coffee control and Ovaltine control groups were 0.09 (0.11%) p value 0.998 and0.41 (0.49%) p value 0.06 respectively. Conclusion: Coffee and Ovaltine consumption leadsto modest increases in heart rate. Safe usage of these beverages need to be evaluatedespecially in patient with conditions precipitating with increase in heart rate. More clinical research is required to formulate guide lines for safe consumption in patients with heartdiseases.
