Hairmyres Hospital in East Kilbride is to become the centre for serious heart attack victims in Lanarkshire and much of Ayrshire - inlcuding Carrick - while the Golden Jubilee National Hospital in Clydebank will serve Greater Glasgow and Clyde.
Potentially this could see some Carrick residents facing a lengthy ambulance journey to East Kilbride - and also being taken past two fully operational A&E units at Ayr and Crosshouse on the way.
Concerned MSP Cathy Jamieson hit out: "The proposed changes to local ambulance services are especially concerning following reports in the national press that all serious heart attack patients in Ayrshire are to be treated at Hairmyres Hospital in East Kilbride.
"This could potentially mean that a patient in Ballantrae could face a 65-mile ambulance journey to receive treatment, bypassing the accident and emergency departments at both Ayr and Crosshouse Hospitals on the way.
"I've contacted the Cabinet Secretary for Health to raise these very serious local concerns."
The concerns of Carrick residents over the proposed changes to paramedic provision in the area were heard at a meeting held in Maybole Town Hall on Monday evening.
Currently, Maybole Ambulance Station operates with one ambulance, three paramedics and two technicians but under the new proposals there would be five paramedics with one 4x4 vehicle.
Many locals feel this would is a downgrading of provision.
One North Carrick resident said: "The proposals don't improve the service in the area, in fact I think it will leave it more stretched.
"What is the point of sending a vehicle to an emergency that can't take them to hospital? It doesn't make any sense."
Chair of Maybole Community Council, Peter Mason, was delighted with the attendance at the meeting despite short notice.
He said: "There was a decent turnout at the meeting for what is a controversial subject. There were representatives from throughout Carrick.
"The Scottish Ambulance Service also came and a paramedic with a fast-response vehicle attended and it allowed people to have a good look at the vehicle.
"We were given assurances that there would be a public consultation prior to any decision being made, which I was delighted with."
Mr Mason was keen to stress that this was not just an issue for Maybole but for all of Carrick and that needs are greater in the area with it being so rural.
Local MSP Ms Jamieson attended the meeting and said afterwards: "The significant number of people at the meeting in Maybole shows the level of concern over these changes.
"Any proposals from the Scottish Ambulance Service which will cut the provision of ambulance and paramedic services to any of the communities in my constituency is completely unacceptable.
"There are real concerns about where the back-up ambulances would come from, particularly if the Girvan ambulance was out on call.
"I am disappointed that the Scottish Ambulance Service chose not to consult with the local community before making these plans known in the press and they need to address these concerns urgently.
At the meeting the ambulance service gave an assurance that no decision had yet been taken, and that a proper consultation would now be held."
