A STEMI Protocol for Muskoka and Cottage Country

Ontario’s 15 cardiac catheterization labs and the interventional cardiology teams that staff them represent a significant investment in achieving the best possible outcomes for ST-Elevated Myocardial Infarction (STEMI) patients. Paramedics are equipped and trained to recognize STEMI heart attacks and transport patients to the regional cath lab with a goal of achieving the international gold standard time of 90 minutes door-to-balloon (DTB) – that is 90 minutes from when the Paramedics make patient contact to when the Cardiologist restores blood flow to the affected part of the heart by inflating the balloon at the tip of the catheter. Patients that are treated at a cath lab within the 90 minute window enjoy significantly improved short, medium and long term outcomes for both return to a good quality of life and survival.

The vast majority of Ontarian’s, as many as 12 of 13.5 million residents, live within the 90 minute catchment of a regional cath lab when transported by land ambulance. One notable exception is the tens of thousands of people that migrate to Muskoka and cottage country during the summer months, especially on weekends. By design cottages are remote places and access is complicated by kilometres of twisting gravel roads and in many instances the need to cross water. Achieving 90 minute DTB times using land ambulance is not possible from most cottages. The cath labs at South Lake in Newmarket and Health Sciences North in Sudbury are tantalizingly close but not quite attainable. Even the proposed cath lab at Royal Victoria in Barrie will lie outside the 90 minute window for most of cottage country. The new cath lab at Peterborough is now accessible from many cottages in the Kawartha Lakes and Haliburton regions, but certainly not all.

It is the right time to consider the viability of having an air ambulance dedicated to Muskoka and cottage country, perhaps only as a May to September program, perhaps only from Friday to Monday. The appropriate first step is a review of EMS call volumes for the past several years, looking at calls – cardiac, trauma and other – where air ambulance was requested or where the patient may have benefited from air ambulance. If the data suggests that call volumes warrant a dedicated helicopter for Muskoka a deployment strategy should be developed. This may involve having a helicopter based out of Muskoka Airport in Bracebridge during peak volume periods.

The high cost of building and maintaining Ontario’s world class STEMI response program has been met. The cost of providing access to the program for tens of thousands of people that have a permanent residence within the 90 minute window but spend a significant number of days each year cottaging or vacationing on the periphery is incremental.  A dedicated air ambulance for Muskoka, tasked with getting STEMI patients to the cath lab within the 90 minute window, should be viewed as a value added proposition, not an expense. It was the tax dollars of the people in cottage country that in no small part funded the development of the Province’s STEMI program, it seems only fair that a relatively few additional dollars be invested to provide them with year round access.

The true value of an air ambulance access program will be realized when patients that would have been left debilitated (or dead) and facing months of expensive rehab are now coming home within days of their MI with little or no loss of heart function, little or no death of heart muscle and enjoying a rapid return to a lifestyle that in many cases is better than what they were experiencing pre-heart attack.  The cost saving to the healthcare system when these outcomes are achieved is significant.

Leading Cause Prevention Strategies, along with many other CPR and First Aid training agencies and local EMS services, is dedicated to providing Cottager’s with the knowledge and tools to achieve the best possible outcomes for cardiovascular emergencies. The first step in achieving good outcomes is early recognition and management of the warning signs and symptoms of heart attack, stroke and cardiac arrest. Even if first responders restore a blood pumping rhythm to a cardiac arrest patient with early CPR and early Defibrillation patient outcome is compromised if there is no early access to advanced care. Even if first responders recognize the signs of heart attack and Call 911 immediately, patient outcome is compromised if there is a delay in restoring blood flow to the affected part of the heart. The work that we do helping Lake Associations and cottage families build cardiac safe environments will be lost if patients do not have rapid access to advanced care and cardiac cath labs.
