At CREATION.co we track trends and gather insights into the online conversations and engagement surrounding congress events. This week we tracked the online conversation between HCPs around the American College of Cardiology (ACC25).

From March 15th, two weeks before the conference started, HCPs actively engaged online, generating buzz around cardiovascular advancements. More than 400 HCPs shared their excitement about attending the conference, contributing to 1,259 posts before it even began.

By March 29th, many had begun sharing their experiences from Chicago, posting guides to navigate clinical trials, resources for early career professionals, and highlights of key sessions and speakers. Discussions covered a range of topics, including advancements in AI and the role of social media in professional development. 

By the end of the conference, more than 1,800 HCPs generated over 8,000 social media posts.

On March 29th, there was a notable spike in online conversations driven by mentions of different trials and key sessions. WARRIOR trial was mentioned 35 times followed by STRIDE, with 45 HCP mentions. Cardiologist Hany Ragy, who ended up being the most active HCP through the conference, posted 62 times that day, with 18% of those posts mentioning those trials. 

Other spikes in the conversation were driven by unique factors each day such as product mentions including Semaglutide and Dapaglifozin and different hashtags used throughout the conference, such as #cardiotwitter, #heartfailure. Additionally, research presented in a Late-Breaking Clinical Trial (LBCT) sessions were also a key contributor to the high volume of conversation, specially around the context of heart failure. 

ACC25 saw substantial online activity from HCPs worldwide, US HCPs were the most active followed by Spain and UK HCPs. HCPs from the US contributed to 62% of the online conversation, while HCPs from Spain accounted for 5% and the UK for 4%.

Notably, 2 of the most active HCPs, Cardiologist Hany Ragy from Egypt  and Eolo Morandi Jr from Brazil, emerged as top contributors. Eolo Morandi posted 161 times, generating 77% of mentions from Brazilian HCPs, while Hany Ragy posted 189 times, accounting for 89% of Egyptian HCP engagement. 

Unsurprisingly, scientific sources were the most trusted in the online conversation. HCPs frequently cited accounts such as ACCintouch and renowned journals like JACC and NEJM. The most widely shared post was from NEJM, titled “Oral Semaglutide and Cardiovascular Outcomes in High-Risk Type 2 Diabetes,”  with 108 HCP shares, reaching 1,551,083 accounts worldwide.

Additionally, HCPs frequently acknowledged their peers on their posts. Cardiologist Martha Gulati, a previously identified DOL by CREATION.co, was the most referenced individual, followed by Mamas A. Mamas, another key voice in the space.

HCPs used hashtags to discuss cross-disciplinary topics, gender representation, and key cardiovascular research. Unsurprisingly, #ACC25 was the most used hashtag, followed by #CardioTwitter, an online community where HCPs share knowledge with peers.

The #ACCFit hashtag was primarily used in discussions about leadership development in cardiology. Meanwhile, #ACCWIC highlighted the Women in Cardiology sessions, which focused on breaking barriers, strengthening networks, and promoting mentorship for female professionals. Many female HCPs shared photos from these sessions, celebrating colleagues, exchanging ideas, and fostering a supportive community.

Among manufacturers, Novo Nordisk was the most mentioned, with a few HCPs discussing the competitive landscape in the obesity space. Merck ranked second, with online conversations focusing on its partnership with ACC and phase 3 ZENITH trial results.

The online activity around ACC 2025 emphasizes how crucial it is to follow along with online conversations in order to get the most out of a medical congress.
