Cardiology is the medical speciality dealing with the diagnosis and treatment of diseases and disorders of the heart.

Cardiologists are specialists in diseases of the heart. The biggest area of heart disease they treat is coronary artery disease e.g. angina and chest pains. They also treat abnormal heart rhythms, heart failure, high blood pressure and some rarer conditions.

Many different cardiology diagnostic tests are available, including echocardiogram and angiogram. Treatment can then fall into one of three areas:

  • drug therapy
  • interventional procedures (e.g. coronary angioplasty and pacemaker implants)
  • cardiac surgery

Description of service

The cardiology department provides a full range of cardiac diagnostic tests and inpatient and outpatient services.

Northwick Park Hospital has a catheter laboratory in which angiograms and angioplasties are performed. The majority of patients from Central Middlesex Hospital will also have their angiograms and angioplasties performed at Northwick Park, although some cases will be referred to St Mary’s Hospital. Both Northwick Park and Central Middlesex perform pacemaker implants and run pacemaker clinics.

Both hospitals also run one-stop-shop outpatient clinics where all basic diagnostics are performed on the day of the first consultation. They also have coronary care units for dedicated, specialist cardiac inpatient care and operate rapid access chest pain clinics, in which patients are seen within 14 days of GP referral. We work closely with the local GPs with a special interest in cardiology and have a team of specialist cardiac nurses.

The Trust does not provide cardiac surgery but has excellent links with St Mary’s Hospital and Harefield Hospital where the majority of patients requiring cardiac surgery are transferred.

The cardiology department has a special interest in nuclear cardiology and echocardiography. The echocardiography department at Northwick Park Hospital has been granted ‘centre of excellence’ status in the UK for transthoracic, transesophegeal and stress echo, following a formal visit by the British Society of Echocardiography.
