The use of invasive hemodynamic monitoring is based on the following principal factors: 1. Difficulty in interpreting clinical and radiographic findings of pulmonary congestion even after a thorough review of noninvasive studies such as an echo-cardiogram. 2. Need for identifying noncardiac causes of arterial hypotension, particularly hypovolemia. 3. Possible contribution of reduced ventricular compliance to impaired hemodynamics, requiring judicious adjustment of intravascular volume to optimize left ventricular filling pressure. 4. Difficulty in assessing the severity and sometimes even determining the presence of lesions such as mitral regurgitation and ventricular septal defect when the cardiac output or the systemic pressures are depressed. 5. Establishing a baseline of hemodynamic measurements and guiding therapy in patients with clinically apparent pulmonary edema or cardiogenic shock. 6. Underestimation of systemic arterial pressure by the cuff method in patients with intense vasoconstriction. The prognosis and the clinical status of patients with STEMI relate to both the cardiac output and the pulmonary artery wedge pressure. Patients
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
