Determining the Cause of Coronary Vasomotor Disorders in Patients With...

Approximately 30% to 50% of patients who are referred for diagnostic coronary angiography are found to have no obstructive coronary artery disease (CAD). Ischemia and nonobstructive coronary arteries (INOCA) is increasingly recognized and encompasses coronary microvascular dysfunction, vasospastic angina, symptomatic myocardial bridging, and other vasomotor disorders. However, the prevalence of these disorders and whether underlying atherosclerotic plaque burden and morphology affect the long-term outcomes of each physiologic phenotype is unknown.

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.

Real Patient Stories

Suzanne’s story

In February 2020, I had a VF cardiac arrest.

My memories start a week after the event when I awoke in ICU.

I was confused and initially unable to move. My family were at my bedside and told me what had happened.

Amazingly, I had survived not only the arrest, but also aspiration pneumonia, sepsis and a stage 3 acute kidney injury requiring dialysis.

Mary’s story

First came the headaches – worse than migraines – then the shortness of breath and having to lay down after crossing the room.

Five months after my symptoms began, I was diagnosed with a 99% blockage in my LAD and 99% blockage in an artery branch off that.

I was stented and, in doing so, they jailed an artery. I was given Metoprolol and I got worse.

I underwent another Angiogram, and all was fine, so they changed my medication and I began to use my Nitro more.

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.
