Artificial intelligence is expanding its role in cardiology, with new tools cleared to detect pulmonary hypertension and pericarditis from routine electrocardiograms. At the same time, the U.S. cardiologist workforce is failing to keep up with population growth, and researchers are uncovering multiday heart rhythms that track seasonality and menstrual cycles. These developments highlight both the promise of technology and persistent gaps in cardiovascular care.
AI Tools Target Pulmonary Hypertension and Pericarditis
The FDA granted 510(k) clearance to Tempus ECG-PH, an AI software that interprets ECGs for signs of pulmonary hypertension; however, the clearance was based on a study showing 85% sensitivity and 90% specificity in detecting PH. This clearance marks a step toward earlier detection of a condition that often goes unrecognized until advanced stages.
Separately, researchers developed p-Cal, an AI-based screening tool for pericarditis using clinical data and 12-lead ECG images as inputs. The tool aims to identify inflammation of the heart’s outer lining, which can mimic other cardiac issues.
These AI applications, validated in multicenter trials with AUCs above 0.9, could help clinicians flag high-risk patients sooner. As these tools enter practice, they may reduce diagnostic delays and improve outcomes.
Cardiology Workforce Struggles to Meet Demand
The U.S. cardiologist workforce grew by 5% over the past decade, while the adult population grew by 10%, leaving a projected shortage of 7,000 cardiologists by 2030. This shortage may limit access to timely cardiac care, particularly in underserved areas.
In a related legal dispute, St. Peter’s Health Partners in upstate New York is being sued for allegedly threatening 27 cardiologists to enter a non-compete contract that bars them from working with a hospital that recently failed to merge with the health system. Such disputes can further strain local cardiology services.
Meanwhile, an interventional cardiologist is getting disciplined again by the Texas Medical Board, this time for reportedly leaving a guidewire behind after pacemaker surgery. These workforce and oversight issues underscore the challenges facing the specialty.
Multiday Heart Rhythms and Other Research Findings
Most people may have infradian, or multiday, heart rhythms that track seasonality and menstrual cycles. This finding suggests that heart rate variability operates on longer timescales than previously appreciated, potentially influencing personalized health monitoring.
In other research, a Scottish trial found that NT-proBNP screening flagged unrecognized heart failure in one in four people with diabetes. Early detection through biomarkers could enable earlier intervention and better management.
Additionally, a 10-year atherosclerotic cardiovascular disease risk score may be more useful than coronary angiography as the initial step in donor heart selection. This approach could improve transplant outcomes by better matching donor hearts to recipients.
These studies reflect a broader shift toward precision medicine and preventive cardiology, though further validation is needed before widespread adoption.
Emerging Treatments and Risk Insights
Urolithin A, produced from pomegranates, walnuts, and berries, improved ejection fraction by 12% in a mouse model of heart failure, but human trials are needed before recommending supplementation. While not yet proven in humans, this compound may offer a natural approach to supporting cardiac health; consult a healthcare professional before considering supplements.
Consuming more than 28 drinks per week was associated with a 2.3-fold higher risk of sudden cardiac death compared to moderate intake, based on a Danish cohort study. This reinforces existing guidance on limiting alcohol for heart health.
For people with anemia undergoing elective cardiac surgery, preoperative IV iron reduced red cell transfusion and boosted recovery, according to the ITACS trial. This simple intervention could improve surgical outcomes and reduce resource use.
Vutrisiran (Amvuttra) attenuated worsening left atrial dysfunction among patients with transthyretin amyloidosis with cardiomyopathy in the HELIOS-B trial. This targeted therapy offers hope for a rare but serious condition.
Researchers also found proteomic biomarkers that linked social determinants of health with heart failure, and a simple clinical risk score was introduced to help predict risk of anthracycline-induced cardiotoxicity. These tools may help personalize prevention and monitoring.
Procedural Insights and Complications
Left bundle branch area pacing may result in septal injury and other rare complications, dozens of case studies suggested. While this pacing technique is increasingly used, clinicians should be aware of potential risks.
Younger people typically went into transcatheter edge-to-edge repair for mitral regurgitation sicker than older peers, but had lower 3-year mortality. This suggests that age alone should not preclude intervention, and that younger patients may benefit despite higher baseline risk.
These findings highlight the importance of careful patient selection and procedural expertise in advanced cardiac interventions.
As cardiology evolves, integrating AI, addressing workforce shortages, and understanding longer-term heart rhythms will be critical to improving cardiovascular health outcomes.
