Case Report
A beforehand wholesome 25-year-old Caucasian male with previous medical historical past important just for nephrolithiasis introduced to Monmouth Medical Middle with complaints of palpitations for the previous sooner or later. The affected person has no recognized cardiac historical past, no different danger elements for atrial fibrillation, non smoker, no illicit drug use, occasional alcohol drinker. Roughly, two days previous to his presentation the affected person began consuming an over-the-counter pre-workout vitality complement [Table/Fig-1]. He acknowledged that he had began to devour this complement for higher focus and to extend his stamina for his exercise. On the day of admission, the affected person had gone out for a fishing journey within the morning after consuming one other two capsules of the identical pre-workout complement. He developed palpitations and shortness of breath on the fishing journey and was involved about his signs. He introduced himself to the Emergency Division (ED) for additional analysis and remedy.
On admission, he denied any additional complaints. His vitals have been steady aside from his fast coronary heart price of 140 bpm which was irregularly irregular. He was not in acute misery and his Electrocardiogram confirmed atrial fibrillation with fast ventricular response, price of 123 bpm, regular axis, and no ST-T wave adjustments [Table/Fig-2]. Bodily examination was outstanding for have been unremarkable, his thyroid features have been within the regular vary, urine and serum toxicology display screen have been adverse for any medication or illicit substances. In regards to the Electrocardiogram and bodily examination findings a analysis of recent onset atrial fibrillation with fast ventricular response was made.
The affected person was administered intravenous diltiazem boluses within the ED and was began on a diltiazem infusion for price management of his atrial fibrillation.

Given the affected person’s unremarkable echocardiogram, unremarkable labwork and absent cardiac historical past together with no different danger elements for atrial fibrillation the reason for his new onset atrial fibrillation was attributed to his consumption of over-the-counter vitality capsules.

Dialogue
Over-the-counter stimulants are simply accessible within the type of drugs, vitality drink, liquid capsules and vitality photographs. One of many main constituents of those preparations is caffeine. The quantity of caffeine current in these over-the-counter vitality dietary supplements are in extra in comparison with the usual FDA permitted tips for portions’ of caffeine [Table/Fig-1]. These are broadly aimed on the youngsters and younger adults. A number of research recommend that vitality drinks could function a gateway to different types of drug dependence [1].
Plenty of caffeine formulations can be found out there starting from common espresso to vitality dietary supplements with concentrated quantities of caffeine, with the content material starting from 50 mg to 505 mg per serving. The estimated common every day grownup caffeine consumption is 300 mg. The generally used vitality drinks include three to 4 instances the caffeine as a typical carbonated beverage and promise to spice up efficiency and improve metabolism. It’s broadly believed that the principle mechanism of motion of caffeine within the central nervous system is the antagonism on the degree of Adenosine receptors. Caffeine may act as a drug of abuse by oblique stimulation of the dopaminergic receptors by elimination of the inhibitory impact of adenosine on these receptors. Current research have additionally proven that pre-exposure to caffeine could exert an impact on the classical medication of abuse [2–4]. On account of this motive caffeine has been thought of as an atypical substance of abuse as per DSM 4 TR and DSM 5. Critical toxicities reminiscent of seizure and cardiac arrhythmias inflicting demise have been recognized to be related to consumption of caffeine at concentrations greater than 80 mg/l. The signs related to such complication are normally dizziness, chest ache, shortness of breath, palpitations, syncope and even sudden demise [5]. Excessive doses are recognized to trigger cardiac arrhythmias and this danger is elevated when the particular person has underlying structural coronary heart illness [6]. The vitality complement that our affected person consumed has round 100 mg of caffeine per capsule and the standard dose advisable by the producer is round 2 to three drugs which provides upto round 200 mg to 300 mg of caffeine.
The assorted substances in our sufferers’ vitality complement aside from caffeine and their studied antagonistic results have been proven in [Table/Fig-3]. The substances talked about listed here are plant extracts with a number of pharmacological results and clear proof supporting the usage of such merchandise are missing within the literature. Many of those substances have pharmacological properties much like caffeine and few of them include caffeine. Along with the 100mg of caffeine per capsule, if we additionally take into account the added caffeine from these substances, the whole quantity of caffeine per serving (2 to three drugs) could vary from 300 mg to 500 mg of caffeine perserving. If an individual consumed this round 2 to three instances a day the whole caffeine consumption in a day could vary from 900 mg to1500 mg. The consumption of caffeine in extreme quantities with a mixture of such substances with unknown pharmacological results and unstudied interactions is a serious explanation for concern. No matter which, consumption of such over-the-counter stimulant medication, vitality drinks and vitality photographs containing excessive quantities of caffeine and different elements have proven to have elevated danger in cardiovascular issues [6–10].
Remedy of extreme caffeine intoxication is mostly supportive, offering remedy of the speedy signs, but when the affected person has very excessive serum ranges of caffeine, then peritoneal dialysis, haemodialysis, or haemofiltration could also be required. Administration of seizures with benzodiazepenes or barbiturates may additionally be required. Different managements embrace substitute of electrolytes and fluids to compensate for fluid and electrolyte losses as a result of vomiting and stop renal damage/rhabdomyolysis.
Caffeine in reasonable doses is properly tolerated and there may be subsequently no motive to limit ingestion of caffeine however solely when consumed in excessive doses they develop into arrythmogenic [17]. Just like caffeine, different stimulating brokers reminiscent of leisure medication, nicotine and alcohol might additionally result in probably harmful cardiac arrhythmias. It’s widespread amongst youngsters to devour drug cocktails in events reminiscent of cocaine, amphetamines, ecstasy that are sympathomimetics and will result in cardiac arrhythmias [18]. The arrythmogenic results of alcohol are nonetheless unclear. There might be a subclinical coronary heart muscle damage from persistent use inflicting patchy delays in conduction. Additionally, the hyperadrenergic state of ingesting and withdrawal state, electrolyte abnormalities, impaired vagal coronary heart price management, repolarization abnormalities with extended QT intervals and worsening of myocardial ischemia are the opposite elements that result in arrhythmias in heavy alcoholism [19]. Not like in our affected person who’s an occasional alcohol drinker, it’s clear that his arrhythmia was not secondary to alcohol consumption. Whereas the impact of cigarette smoking on the development of atherosclerotic illnesses is established and properly studied, the position of cigarette smoking on cardiac arrhythmia is much less clearly outlined. The constituents of cigarette smoke reminiscent of carbon monoxide and likewise the oxidative stress brought on by them are more likely to trigger arrhythmias and likewise, the systemic illness prompted as a result of smoking reminiscent of coronary artery illness and likewise persistent obstructive pulmonary illness, which can result in cardiac arrhythmias by themselves [20]. Our affected person was a non smoker to start with and therefore that might not have been the reason for his arrhythmia.
The follow-up of this affected person in 2 weeks after discharge was reassuring with none additional issues. It was evident that the affected person’s cardiac arrhythmia was triggered as a result of consumption of over-the-counter stimulant vitality capsules which had extreme content material of caffeine. The affected person additionally refrained himself from the usage of over-the-counter stimulant medication.
Conclusion
Cardiac arrythmia is usually a uncommon however deadly complication secondary to the consumption of over-the-counter stimulant medication containing excessive quantities of caffeine. Caffeine when current with different substances may cause varied deadly unwanted effects as a result of interactions. Therefore, it’s suggested that manufactuers should clearly state the quantity of caffeine per serving of their product, the well being dangers related to consumption of caffeine and likewise point out the unwanted effects as a result of extra substances.
