Cardiovascular Institute of the South

What Cardiovascular Institute of the South does

Cardiovascular Institute of the South (CIS) is a private, physician-owned and physician-led cardiovascular care provider founded in 1983 and headquartered in Baton Rouge, Louisiana. The organization operates 23 owned clinic locations across Louisiana and Mississippi, staffed by 63 board-certified cardiologists plus advanced practice providers and support staff, with total headcount in the 501-1,000 range. CIS diagnoses and treats the full cardiovascular spectrum — cardiovascular disease, arrhythmias, peripheral artery disease, valve and structural heart disease, and vein disease — through a horizontally integrated care model that spans community screenings, in-clinic diagnostics, an Ambulatory Surgery Center, an Intensive Cardiac Rehab program, a Leg & Vein Center, and an Xpress Care urgent-care clinic.

The company's product portfolio combines in-person clinical services with three care-delivery extensions: a 24/7 Virtual Care Center for round-the-clock telemedicine access, a Cardio@Home remote monitoring program staffed by nurses who track patient blood pressure and medication updates, and a Telecardiology Partners program that provides remote cardiology consultations and interpretations to affiliated hospitals and clinics lacking on-site specialists. A Patient Portal gives patients access to records, test results, and provider messaging. The organization also runs an active cardiovascular clinical research trials program offering experimental therapies.

CIS makes money primarily through fee-for-service clinical care — evaluation and management visits, diagnostic testing, interventional procedures, and facility fees billed to insurance — supplemented by service-agreement revenue from Telecardiology Partners. Specific pricing is not publicly disclosed; costs vary by insurance coverage, service, and treatment plan, and the organization offers a payment portal for patient billing. Patient acquisition is driven by physician referrals, community presence, free cardiovascular screening events, word-of-mouth, and insurance network participation rather than traditional digital marketing. Sub-brands include Cardio@Home, Leg & Vein Center, Xpress Care Clinic, the CIS Blog, and The Cardiovascular Pulse newsletter.
