1 in 15 Older Black Adults With Heart Failure Had Undiagnosed Amyloidosis

In a study of 646 older Black and Hispanic adults with heart failure, 7% had a treatable but often-missed heart condition called cardiac amyloidosis. The rate was highest in Black men over 75, where 1 in 6 had it. About half of cases were tied to an inherited gene variant common in Black Americans, while the other half occurred without any genetic cause.

What the trial was testing

The SCAN-MP enrolled 646 patients with amyloidosis. The study was sponsored by Mathew S. Maurer, MD and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.

What the results showed

Among Black men over 75 with heart failure, 17% had cardiac amyloidosis.

JAMA cardiology · 2025 · NCT03812172

These findings — that had cardiac amyloidosis causing their heart failure — were published in the JAMA cardiology and represent the headline result of the study.

Researchers tracked outcomes across 646 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with amyloidosis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

If you're Black and over 75 with heart failure, there's a meaningful chance you have this condition — and it's treatable with medications that can slow heart damage. The study found that half of people carrying a common gene variant (V142I) developed this disease. Ask your cardiologist about testing for cardiac amyloidosis, especially if your heart failure symptoms don't match typical patterns. Early diagnosis matters because treatments exist.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

A Prospective Cohort Study on Primary Cutaneous Amyloidosis

The aim of this clinical trial is to find out whether the combination of tocilizumab tablets and acitretin capsules is more effective than acitretin capsules alone in treating primary cutaneous amyloidosis. It will also investigate the safety of the combination of tocilizumab tablets and acitretin capsules. The main questions it aims to answer are: 1. Does the combination of tocilizumab tablets and acitretin capsules relieve the pruritus symptoms of the participants faster and reduce the pruritus score more than acitretin capsules alone? 2. What medical problems will the participants encounter when taking tocilizumab tablets combined with acitretin capsules? The researchers compared the combination of tocilizumab tablets and acitretin capsules with acitretin capsules alone to see if the combination could better treat primary cutaneous amyloidosis without causing serious adverse reactions. Participants will: 1. Take the combination of tocilizumab tablets and acitretin capsules or acitretin capsules alone every day for 16 weeks. 2. Visit the clinic once every 4 weeks for checkups and tests. 3. Observe participants at 4 weeks, 12 weeks and 24 weeks after discontinuation of medication to determine the recurrence status. 4. Collect the visual analogue scale (VAS) scores for pruritus, symptom severity (SCORAD) scores , rash area and severity, treatment response (EASI) scores, dermatological quality of life index (DLQI), and insomnia severity index (ISI) of participants before and after treatment.

Artificial Intelligence Guided Echocardiographic Screening of Rare Diseases (EchoNet-Screening)

Despite rapidly advancing developments in targeted therapeutics and genetic sequencing, persistent limits in the accuracy and throughput of clinical phenotyping has led to a widening gap between the potential and the actual benefits realized by precision medicine. Recent advances in machine learning and image processing techniques have shown that machine learning models can identify features unrecognized by human experts and more precisely/accurately assess common measurements made in clinical practice. The investigators have developed an algorithm, termed EchoNet-LVH, to identify cardiac hypertrophy and identify patients who would benefit from additional screening for cardiac amyloidosis and will prospectively evaluate its accuracy in identifying patients whom would benefit from additional screening for cardiac amyloidosis.
