ABSTRACT
Background: The correlation between consumption of Ovaltine and
Coffee with change in heart rate in healthy population has limited and
controversial figures. Increase in heart rate tend to increase work load
of heart and it could worsen condition in people with diseased heart.
Methods: This was nonrandomized prospective open labeled parallel
groups study carried out at MIMC. The sample size of the study was
based on 128 subjects (62 Ovaltine and 66 Coffee) and same number
of controls for Ovaltine and Coffee respectively in a cross over as
negative control. The study was based on 4 groups A, B, C and D were
Coffee control, Coffee, Ovaltine control and Ovaltine respectively.
Subjects with history of heart diseases, medication effecting heart rate
and anxiety disorders were excluded from the study. The unwanted effects were noted during
the 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 mean
heart rate of Coffee control and Ovaltine control groups were 0.09 (0.11%) p value 0.998 and
0.41 (0.49%) p value 0.06 respectively. Conclusion: Coffee and Ovaltine consumption leads
to modest increases in heart rate. Safe usage of these beverages need to be evaluated
especially 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 heart
diseases.
