Terminology

Infective endocarditis (IE) is an infection of the heart's inner lining (the endocardial surface), which may include valves and chordae tendineae.

IFG is Impaired Fasting Glycaemia/Hyperglycaemia. Like IGT, IFG is known as 'prediabetes'.

IFG is defined as a fasting plasma glucose between 6.1 and 6.9 mmol/L (source: NICE).

IFG is managed by lifestyle intervention.

Like IFG, IGT is a form of 'prediabetes'.

The current WHO diagnostic criteria for IGT are: a fasting plasma glucose of less than 7.0 mmol/L and a 2-hour venous plasma glucose (after ingestion of 75 g oral glucose load) of 7.8 mmol/L or greater, and less than 11.1 mmol/L. (source: NICE)

IGT is a strong risk factor for developing diabetes and cardiovascular disease, and therefore IGT is managed using lifestyle change ± medication.

Interstitial lung disease (ILD) refers to a group of diseases affecting the lung interstitium (the tissue and space around the alveoli).

Internal Medicine Training (IMT) replaced Core Medical Training (CMT) in August 2019. This new curriculum was introduced in response to the recommendations set out in the Shape of Training Report, and other drivers.

IMT forms the first three years of post-foundation training and, for the main specialties supporting acute hospital care, an indicative 12 months of further internal medicine training will be integrated flexibly with specialty training in a dual programme.

IMT aims to prepare doctors for the management of the acutely unwell patient, with an increased focus on chronic disease management, comorbidity and complexity. Generic professional capabilities (GPCs) as set out in the GMC's framework will be embedded in all curricula to emphasise the importance of these professional qualities as well as helping to promote flexibility in postgraduate training.

The international normalised ratio (INR) is a laboratory measurement of how long it takes blood to clot, used to monitor individuals taking the anticoagulant warfarin.

INR is derived from the prothrombin time, which evaluates the extrinsic pathway and common pathway of coagulation.

Idiopathic pulmonary fibrosis (IPF) is a progressive condition causing lung scarring, making breathing increasingly difficult.

IPF is the most common type of pulmonary fibrosis.

The clinical course of IPF can be unpredictable, but its five-year survival from diagnosis is comparable to, or even worse than, a number of common cancers.

Intravenous (IV) means existing within or administered into a vein or veins.

NICE Clinical Guideline (CG174) - Intravenous fluid therapy in adults in hospital

The inferior vena cava (IVC) is a large vein that returns deoxygenated blood from the lower and mid body to the right atrium of the heart. Valves prevent backflow due to gravity.

Intravenous immunoglobulin (IVIG) is a therapy for autoimmune disease, including GBS.
