HEART DOCTORS IN CHIKKAJALA, BANGALORE; Pulmonary hypertension Pulmonary hypertension is an uncommon but important cause of dyspnoea. Many patients with this chronic and often severe illness will have raised pulmonary artery pressures as a result of a cardiac or respiratory illness. Other patients may present with increasing dyspnoea without an obvious cardiac or respiratory problem. Idiopathic (primary) pulmonary hypertension (IPH) is diagnosed only when other causes of pulmonary hypertension have been excluded. By definition, pulmonary hypertension is present when the mean pulmonary artery pressure (PAP) exceeds 25 mmHg at rest or 30 mmHg during exercise. The classification of pulmonary hypertension has been revised. The Venice classification was released in 2003. The term ‘primary pulmonary hypertension’ has been replaced with ‘idiopathic pulmonary hypertension’ . Patients may have used fenfluramine or phenermine (appetite-suppressing drugs), or both. Use of these drugs for long periods has been associated with the greatest risk of developing pulmonary hypertension. In cases of IPH there may be a family history (6%; autosomal dominant condition with incomplete penetrance, 20–80%). The majority of familial cases are associates with a mutation on the BMPR2 gene. There may be associated symptoms including fatigue, chest pain, syncope and oedema. Cough and haemoptysis can be present.
POPULAR CARDIOLOGIST IN AMRUTHA HALLI , BANGALORE Assessment of patients with hypertension A patient with definite or possible newly diagnosed hypertension needs at least a basic clinical assessment to look for possible aetiology, severity and signs of complications. The history Questioning should be directed towards the following areas. 1 Past history. Has hypertension been diagnosed before? What treatment was instituted? Why was it stopped? 2 Secondary causes. Important questions relate to: • a history of renal disease in the patient or his or her family, recurrent urinary tract infec-­ tions, heavy analgesic use or conditions leading to renal disease (e.g. systemic lupus erythematosus (SLE)) • symptoms suggesting phaeochromocytoma (flushing, sweats, palpitations) • symptoms suggesting sleep apnoea • muscle weakness suggesting the hypokalaemia of hyperaldosteronism • Cushing’s syndrome (weight gain, skin changes) • family history of hypertension. 3 Aggravating factors: • high salt intake • high alcohol intake • lack of exercise • use of medications: NSAIDs, appetite suppressants, nasal decongestants, monoamine oxidase inhibitors, ergotamine, cyclosporin, oestrogen-containing contraceptive pills • other: use of cocaine, liquorice, amphetamines. 4 Target organ damage: • stroke or transient ischaemic attack (TIA) • angina, dyspnoea • fatigue, oliguria • visual disturbance • claudication. 5 Coexisting risk factors: • smoking • diabetes • lipid levels, if known

THE BEST CARDIOLOGISTS IN YELAHANKA nvestigations of possible or probable stable angina Electrocardiography A standard 12-lead ECG should be obtained in all patients. This is likely to be normal in almost half of patients with subsequently proven coronary artery disease. Nevertheless, an abnormal trace lends weight to the symptoms and favours further investigation. Chest X-ray Routine radiology is not essential but may reveal important co-morbidities. It should always be performed in those with clinical evidence of hypertension, pericarditis (p. 174), heart failure or valvular disease, if only as a baseline. It is similarly indicated for patients with suspected or known pulmonary or systemic disease such as rheumatoid arthritis, COPD or alcoholism. Routine blood tests All patients with suspected angina should have the following routine investigations at presentation (NHF grade A recommendation): n fasting lipids, including total cholesterol, LDLs, HDLs and triglycerides—risk factors n fasting blood sugar—risk factor n full blood count—anaemia exacerbates angina n serum creatinine—impaired renal function is a risk factor and can be worsened by some cardiac investigations. If indicated clinically, thyroid function
