When looking to sell your healthcare product, software, or service to physician group practices, it’s essential to narrow your scope for more efficient marketing and sales targeting. Targeting the largest cardiology physician groups can often be an effective sales strategy.
How many cardiology physician group practices are there in the U.S.?
According to our database, there are more than 2,500 active cardiology physician group practices in the U.S. Many of these groups are multispecialty organizations, with cardiology identified as the primary specialty based on the most common specialty among the physicians associated with the practice.
Why target cardiology physician groups?
Large cardiology groups are prime targets for healthcare solutions. With cardiovascular disease as a leading global health burden, these groups offer a stable patient base, high service volumes, and strong revenue potential, representing high-value opportunities.
There is also value in targeting physician groups versus other healthcare organizations. Groups often centralize purchasing decisions, which can lead to bulk sales and long-term partnerships. Additionally, partnering with respected physician groups can enhance credibility, market visibility, and even influence in the market.

Tips for targeting cardiology physician groups
Once you’ve honed in on your target list of cardiology physician groups, it’s essential to remember their key focuses and frame your offering as a solution to their needs. Consider the following to effectively engage cardiology physicians:
Understand their needs
Better understand the unique challenges and priorities of each physician group by drilling into data like procedure and claims data, tech install data, and even Medicare charges. Using these insights, you can prioritize high-impact prospects and personalize your outreach for maximum efficiency.
Highlight relevant benefits
Using your understanding of each physician group’s challenges, highlight the relevant benefits of your product, software, or service. Focus on how your solution can improve patient outcomes, enhance diagnostic capabilities, or optimize operations, and be sure to target your advantages to each physician group instead of having a blanket statement of benefits—they’ll find more value in your product or service when you can show them how it will benefit their specific challenges.
Showcase success stories
Provide evidence of the real-world benefits of your solution. Whether it’s clinical trial data or case studies, select success stories that are most relevant to the needs of the physician group you’re engaging.
