• Recent studies indicate a slight rise in cardiovascular metrics such as blood pressure and heart rate due to common ADHD medications.

  • Despite potential risks, the advantages of ADHD treatments are considered to outweigh the disadvantages, and continuous monitoring could help in managing these risks effectively.

  • There is an ongoing anticipation for more comprehensive data concerning the long-term cardiovascular impacts of ADHD medications.

Recent findings highlight that the minor cardiovascular risks linked to ADHD medications, such as methylphenidate, bupropion, and lisdexamfetamine, are overshadowed by their benefits to mental health.

The investigation, which was detailed in the April 6 edition of The Lancet Psychiatry by a global team of researchers, evaluated 102 randomized control trials involving 13,315 young individuals and 9,387 adults.

Results identified modest elevations in heart rate, blood pressure, and electrocardiogram (ECG) metrics among those treated with stimulants for ADHD. Similar increases were noted among users of noradrenaline reuptake inhibitors, another class of antidepressants. Conversely, alpha agonists were found to decrease both heart rate and blood pressure.

The authors assert that while ADHD medications typically increase indicators of cardiovascular health such as blood pressure and pulse, adhering to current monitoring practices can ensure favorable health outcomes.

Cheng-Han Chen, MD, an interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center in California, emphasized the importance of cardiovascular risk assessment in individuals prescribed ADHD medications. Chen, who did not participate in the study, highlighted the necessity of such screenings, especially given the young age of many subjects in these studies.

Chen explains, “Currently, this research does not suggest a significant change in cardiovascular risks, however, it is advisable to monitor these effects over a prolonged period to better understand long-term outcomes.”

Anoop Singh, MD, a general psychiatrist and regional medical director for Mindpath Health in California, found the study’s outcomes comforting for both patients and healthcare providers. Singh, who was also not involved in the study, commented, “This essentially confirms previous findings and supports continued adherence to clinical guidelines that recommend routine monitoring of blood pressure and heart rate before and during treatment with ADHD medications.”

“The results are not surprising and essentially build upon the findings of prior studies,” added Singh.

Fostering a Cardio-Healthy Lifestyle Despite ADHD

The past decade has seen a marked rise in ADHD diagnoses, reports the Centers for Disease Control and Prevention (CDC).

This increase is attributed to greater public and medical recognition of the disorder. However, some ADHD medications like Ritalin have faced negative perceptions.

When prescribed correctly, these medications improve mental health and overall quality of life. Research from 2019 shows that ADHD medication has reduced instances of injuries and substance abuse, although these findings have their limitations.

“Even common medications such as Sudafed are known to raise blood pressure and heart rate,” remarked Singh.

“But in a healthcare setting, when considering these medications, there is a certain level of trust that should be maintained, given the structured process of evaluating and monitoring for side effects,” he continued.

When evaluating individuals diagnosed with ADHD, Chen noted that cardiologists consider several risk factors before prescribing medication.

“We perform the same screenings for cardiovascular risk factors as we would for any other individual, including high blood pressure, high cholesterol, and diabetes,” explained Chen.

“We also advise patients to maintain a healthy lifestyle by eating a heart-healthy diet, engaging in regular exercise, avoiding tobacco and excessive alcohol consumption, and ensuring sufficient quality sleep,” he added.

Need for Extended Research on ADHD Medications and Cardiac Health

A significant limitation noted by researchers is that none of the studies reviewed extended beyond 26 weeks, with most examining effects over just 12 weeks.

This issue is not unique to psychiatry but is common across various fields of medicine, according to Singh.

“There is a continuous demand for more extensive, long-term studies to provide richer data,” he stated.

In a commentary in Lancet Psychiatry that accompanied the research, Steven R. Pliszka, an unaffiliated researcher, proposed a double-blind study as a potential future approach. This could involve periodic monitoring of cardiovascular indicators more intensively.

Pliszka suggested employing machine learning techniques to sift through vast databases for pertinent data, indicating a possible direction for future research.

The study authors themselves admitted the lack of long-term data and cautioned that while the average increases in cardiovascular measures like blood pressure and pulse were small, they could be more significant in certain individuals and might necessitate medical intervention.
