Targeting the 44% of all CVD patients who are undiagnosed and untreated can be a smart strategy for a cardiovascular medical practice. By focusing on this group, the practice can tap into a large potential patient population, which can help increase revenue and profitability. This strategy can also have positive implications for public health, as it can lead to better outcomes for patients who may otherwise go untreated.

Understanding why patients are reticent to seek cardiovascular care and overcoming those barriers can also have significant positive implications for a cardiovascular medical practice. By addressing patient concerns and removing barriers to care, the practice can build trust with patients and improve patient satisfaction, leading to increased loyalty and patient retention.

Using heart risk targeting to acquire patients with the highest heart risk scores and patient lifetime values can help a cardiovascular medical practice focus on the most high-value patients. This strategy can improve the practice's bottom line by increasing revenue and profitability, as well as lead to better patient outcomes by identifying and treating patients who are at the highest risk for cardiovascular disease.

However, there are also potential challenges associated with these strategies. In terms of competitive issues, other cardiovascular practices may also be targeting these patient populations, which could lead to increased competition for patients. Financially, targeting undiagnosed and untreated patients may require additional resources for outreach and patient education, which can be costly. Additionally, targeting only high-risk patients may lead to neglecting lower-risk patients who may also benefit from cardiovascular care.

In conclusion, these three strategies can have significant implications for a cardiovascular medical practice in terms of competitive issues, financial issues, and patient outcomes. While there are potential challenges associated with these strategies, they can also provide opportunities for growth, improved patient outcomes, and better public health.
