Invasive and non-invasive assessment of ischaemia in chronic coronary syndromes:...

Intracoronary physiology testing has emerged as a valuable diagnostic approach in the management of patients with chronic coronary syndrome, circumventing limitations like inferring coronary function from anatomical assessment and low spatial resolution associated with angiography or non-invasive tests.

The value of hyperaemic translesional pressure ratios to estimate the functional relevance of coronary stenoses is supported by a wealth of prognostic data. The continuing drive to further simplify this approach led to the development of non-hyperaemic pressure-based indices. Recent attention has focussed on estimating physiology without even measuring coronary pressure.

Coronary microvascular dysfunction in stable ischaemic heart disease

Diffuse and focal epicardial coronary disease and coronary microvascular abnormalities may exist side-by-side. Identifying the contributions of each of these three players in the coronary circulation is a difficult task.

Yet identifying coronary microvascular dysfunction (CMD) as an additional player in patients with coronary artery disease (CAD) may provide explanations of why symptoms may persist frequently following and why global coronary flow reserve may be more prognostically important than fractional flow reserve measured in a single vessel before percutaneous coronary intervention.

Real Patient Stories

Charlotte’s story

While at work in September 2014, I lost vision of my left eye and had terrible feeling of “heat” all over the left side of my body.

The ER ophthalmologist directed me to cardiology for a vascular problem.

A week later, I could not walk 100 meters (325 feet) without crushing chest pain and shortness of breath.

I was no longer functional. Making my bed was all I could do in a whole day. I was no longer an active 54-year-old.

Sandra’s story

My story began in January 2010, while sitting at a traffic light returning to the office. I was working as a home health physical therapist. I began having chest pain out of nowhere. I got to my office and my boss, an RN, asked me if I was OK. I told her about the chest pain. By then it was starting to progress down my left arm. She took my blood pressure, normally 98/68. It was 140/90. She called my husband and told him to meet me at the ER. I drove myself there. They ran the normal tests and diagnosed me with costochondritis. Pain meds made the symptoms go away. The pain came back six times in the next 6 months. I asked for a cardiologist referral, but was denied, due to my age (39), lack of family history, and being in shape.

Barbara’s story

I am a 62-year-old retired physician. My story began at age 47.

I was a very busy practicing OB/Gyn physician who was otherwise healthy.

I was on call at the hospital, and it was turning out to be one of the busiest days I had ever experienced as a physician. I was in a medical group that took call for 24 hours straight, most of the time working the entire 24 hours.

Halfway through that 24-hour call, I was in the operating room doing a C/Section on a patient. Halfway through the surgery I began to feel crushing chest pain.
