Why is CHD important?
![Page 4: Inequalities in coronary heart disease treatment Professor Azeem Majeed University College London.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649e245503460f94b13102/html5/thumbnails/4.jpg)
Mortality: Numbers CHD is the single most common cause
of death in both men and women. One in four men and one in six women
die from CHD (about 125,000 deaths in the UK in 2000)
CHD is also the commonest cause of premature death (about 45,000 deaths)
![Page 5: Inequalities in coronary heart disease treatment Professor Azeem Majeed University College London.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649e245503460f94b13102/html5/thumbnails/5.jpg)
Mortality: International Death rate from CHD in the UK is
among the highest in the world Although death rates have fallen in
the UK, rates have fallen more quickly in many other countries
Within UK, rates are highest in Scotland, Northern Ireland and Northern England

Morbidity: Prevalence Calendar year 1998 210 general practices in England &
Wales, part of GPRD 1.3 million patients

Inequalities in CHD Treatment

CHD Treatments Lifestyle changes Drugs for angina Drugs to reduce risk of acute
events: e.g. aspirin & statins Control of risk factors: e.g.
diabetes, high blood pressure Interventions: Angioplasty & CABG

Secondary & Tertiary Care Several studies have examined
equity of access to care Thrombolysis Angiography Angioplasty & CABG Drug treatment on discharge

Older studies Studies carried out in early - mid
1990s Age, sex and socio-economic
differences present Women, elderly, deprived had
poorer access to specialist investigation & treatment

SW Thames: Early 1990s Admissions for CHD in one year Proportion of admissions in which
angiography carried out Proportion of admissions in which
coronary artery bypass graft (CABG) or percutaneous transluminal angioplasty (PTCA) carried out

Newer studies Many studies carried out in late
1990s & early 2000s Show a narrowing of gap between
men & women and elderly & younger patients
Possibly still some socio-economic differences in access to specialist care
![Page 27: Inequalities in coronary heart disease treatment Professor Azeem Majeed University College London.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649e245503460f94b13102/html5/thumbnails/27.jpg)
Possible Explanations Patient & society Clinical trials Primary care Secondary care Tertiary care
![Page 28: Inequalities in coronary heart disease treatment Professor Azeem Majeed University College London.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649e245503460f94b13102/html5/thumbnails/28.jpg)
Proposed solutions Greater awareness among clinicians
and patients More women and elderly in clinical
trials National service frameworks Review of health inequalities Clinical governance Better use of NHS data for monitoring
![Page 29: Inequalities in coronary heart disease treatment Professor Azeem Majeed University College London.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649e245503460f94b13102/html5/thumbnails/29.jpg)
Conclusions Even in a free health care system
like the NHS, some groups have poorer access to care than others
Greater awareness among patients, clinicians, policymakers
Interventions in place to reduce inequalities & discrimination
