Medically reviewed by Dr. For if no accident interferes, but the disease goes on to its height, the patients all suddenly fall down, and perish almost immediately. Of which indeed their frequent faintness and sensations as if all the powers of life were failing, afford no obscure intimation.

All the rest were men near or past the fiftieth year of their age… The termination of the angina pectoris is remarkable. Some account of a disorder of the breast. Medical Transactions. Constantin Hering, in , tested NG in healthy volunteers, observing that headache was caused with 'such precision'.

Hering pursued NG 'glonoine' as a homeopathic remedy for headache, believing that its use fell within the doctrine of 'like cures like'. Alfred Nobel joined Pelouze in and recognized the potential of NG. However, spontaneous coronary spasm episodes are seldom captured on angiography and thus require provocative spasm testing. This involves administration of a provocative vasospastic agent e. The role of coronary microvascular dysfunction CMD as a cause of angina has become more apparent over the past 40 years.

Initially described as the cardiological syndrome X as distinguished from the metabolic syndrome X in patients with typical exertional angina, abnormal stress ECG test, yet normal angiography and no features of coronary spasm. Subsequently, researchers used other modalities to identify the presence of CMD in patients with angina and normal angiography including impaired coronary flow reserve microvascular angina , delayed epicardial coronary artery contrast opacification on angiography reflecting increased distal coronary resistance the coronary slow flow phenomenon , and acetylcholine-provoked chest pain and ischaemic ECG changes in the absence of inducible coronary artery spasm microvascular spasm.

The diagnostic criteria and landmark studies of these CMD disorders are summarised in Table 2. The angina associated with these conditions may mimic the classic Heberden description, but many patients also have unusual characteristics such as prolonged episodes and a variable response to sublingual nitrates. Thus, further evolution in our understanding of angina pectoris will develop with advances in our knowledge of these disorders.

The introduction of percutaneous coronary transluminal angioplasty pioneered by Gruntzig, followed by the development of intracoronary stents in the mid s, revolutionised the treatment of CAD.

Health status is the level of health of an individual as subjectively assessed by the individual, i. This conceptual model of health status is depicted in Figure 1. The measurement of health status is achieved using standardised questionnaires, such as the Short Form SF In the case of angina, the Seattle Angina Questionnaire SAQ has evolved as the gold standard measure of condition-specific health status. In fact, the SAQ is more reproducible than clinician interpretation of coronary angiography [16].

Furthermore, patient-reported health status been shown to be a significant predictor of mortality and hospitalisation in CAD patients [17], underscoring the importance of this indicator in patient care. The range of health status domains in coronary artery disease: symptoms, function, and quality of life. Figure adapted with permission from Spertus et al [18] and Wilson and Cleary [19]. The frequency of angina symptoms may be considered an important determinate of health status.

The patients who reported at least weekly angina also showed more physical limitation and poorer quality of life compared to patients reporting less frequent angina, as shown in Figure 2. Thus, the simple enquiry of how often a patient experiences chest pain provides useful insights into the impact of angina on health status.

This underscores the importance of patient-reported symptoms since clinicians may not accurately estimate the full impact of the angina on the patient. It is also evident that clinical investigations, such as the angiogram, have a limited role in determining patient health status.

Clinical registry data demonstrate that patients undergoing coronary angiography for the investigation of angina have similarly impaired health status regardless of whether obstructive or non-obstructive CAD is revealed [21].

The conventional treatment approach for patients with angina includes the prevention of cardiac events and the improvement in symptoms, although the later should be extended to the more holistic approach of optimising health status. These objectives can be achieved with medical therapy, rehabilitation and support services, and possibly revascularisation procedures, including percutaneous coronary intervention PCI and coronary artery bypass grafting CABG.

The role of these specific therapies varies with the clinical context since acute coronary syndromes are associated with a high risk of further cardiac events in the following 30 days, whereas chronic coronary syndromes have a comparative low risk of cardiac events.

Accordingly, in acute coronary syndromes, medical and revascularisation therapies have a key role in preventing further cardiac events whereas the management of chronic coronary syndromes should particularly focus on the optimisation of health status.

The patients were randomised to medical or revascularisation therapy, with no difference observed in cardiovascular events between these two treatment approaches. Moreover, PCI had only a small incremental benefit in reducing angina symptoms over optimal medical therapy alone.

Accordingly, guidelines [22] and appropriateness use criteria [23] for chronic stable angina recommend utilising optimal medical therapy before consideration of revascularisation therapies. The management of patients with angina has not only evolved to the holistic consideration of health status but also to evaluation of clinical performance criteria.
