That finding pushed the research team to build something that did not previously exist. Rebecca Arden Harris, MD, Sean Hennessy, PharmD, PhD, and colleagues developed what Penn’s Leonard Davis Institute of Health Economics describes as the first heart disease risk calculator designed specifically for patients who use cocaine or methamphetamine. Until now, available calculators were built for the general population.

Why Standard Risk Tools Fall Short for Stimulant Addiction Treatment

Most cardiovascular risk calculators estimate danger over 10 or 30 years, and they were developed using populations that included very few people who use stimulants. Harris said that mismatch can hand clinicians the wrong picture.

A low 10-year score can look reassuring for a patient in their 40s while the actual danger arrives much sooner. The Penn team built their model around a three-year window instead, which they argue better reflects the timeframe in which serious cardiovascular events occur in this population.

Stimulants carry real cardiac consequences. Cocaine and amphetamines can cause sudden spikes in blood pressure, trigger spasms of the coronary arteries, set off dangerous heart rhythms, and damage the heart muscle. According to the Penn report, this often happens in people in their 30s and 40s.

How the Calculator Works

Harris and Hennessy built the model using health records from 6,940 adults with documented stimulant use between 2016 and 2024. The tool was designed to stay simple enough for a routine office visit.

It draws on age, current smoking status, blood pressure, whether the patient uses cocaine only or also methamphetamine, race, and whether the patient already takes medication for heart disease or high blood pressure. It returns a personalized three-year risk estimate and requires no blood tests.

Hennessy said that last detail matters more than it sounds. People who use stimulants often receive fragmented care, so laboratory results such as cholesterol levels are frequently missing from their records. The team designed the tool to work with information available at every clinical encounter. The researchers reported that the calculator showed excellent calibration, meaning its predicted risks closely tracked the heart events that actually occurred over three years.

What the Researchers Say It Cannot Do Yet

The Penn team was direct about the limits of a first attempt. The model was developed using data from a single health system in the Mid-Atlantic, so it needs testing in other populations and regions, particularly in the western United States where methamphetamine use is far more common.

Electronic health records also fail to capture how long or how often a person has used stimulants. Hennessy described the model as a proof of concept rather than a substitute for clinical judgment.

The team has proposed a preliminary clinical framework, but Harris was careful to call it an early idea rather than a consensus guideline. Under that framework, a higher estimated risk could prompt clinicians to consider closer attention to blood pressure, statin therapy where appropriate, referral for cardiac evaluation, and treatment for stimulant use. Whether using the calculator this way actually improves patient outcomes remains to be tested.

What This Means for Treatment Seekers

If you or someone in your family is researching stimulant addiction treatment, this research is a reason to ask providers how they handle physical health alongside substance use. Programs that screen blood pressure, review cardiac history, and coordinate with primary care or cardiology are addressing a risk this study suggests is substantial and fast-moving.

It is also worth asking whether a program can treat co-occurring medical and mental health conditions rather than substance use in isolation. Integrated care is not universal across rehab centers, and it is a fair question to raise before admission.

Finding the Right Rehab

When you compare treatment options for cocaine or methamphetamine use, look at more than the therapy list. Ask which medical services are available on site, whether the program coordinates cardiac follow-up, and how it handles patients who arrive with untreated high blood pressure.

Verify insurance coverage for addiction treatment before admission, and confirm accreditation and clinical credentials directly with the facility. Rehab.com’s directory lists verified treatment centers with details on levels of care, accepted insurance, staff credentials, and specialty programs, so you can compare rehab centers side by side and speak with a treatment advisor about programs that address both stimulant use and cardiovascular health.
