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
THE BEST CARDIOLOGISTS IN YELAHANKA Indications for coronary angiography 1 Angina not responding to medical treatment in a patient without contraindications (e.g. extreme old age—usually older than about 85 these days—or severe co-morbidities) to cardiac surgery or angioplasty. 2 Continuing chest pain whose cause is not clear despite non-invasive investigations. The procedure may well be worthwhile if it reveals normal coronary arteries and prevents a patient being treated unnecessarily with more and more anti-anginal drugs. Non-invasive investigations are more often equivocal in women, and more women than men are found to have normal coronaries at angiography. 3 Preparation of a patient older than 35 or so for some other cardiac surgery (e.g. valve replacement). The surgeon needs to know whether significant coronary disease is present so that coronary grafting can be performed at the time of valve surgery. Otherwise, patients are at risk of ischaemic problems in the post-operative period. 4 Diagnosis of cardiomyopathy (p. 267) by excluding coronary artery disease and infarction as the cause of angina or cardiac failure. These patients may benefit from revascularisation if significant coronary disease is also present (‘ischaemic cardiomyopathy’). 5 Investigation of patients following myocardial infarction. Routine transfer to a centre with angiographic facilities after successful thrombolytic treatment is a grade D recommendation. There is no proof that a patient without continuing ischaemia has an improved prognosis when angiography and revascularisation are carried out routinely after infarction. The Open Artery Trial results suggest there is no benefit compared with optimal medical treatment for patients without ischaemic symptoms in having an occluded vessel opened five days or more after an infarction. However, spontaneous or induced ischaemia (by modified stress testing or perfusion imaging) leads to a grade B recommendation for angiography and intervention. The management of post-infarct patients is definitely easier if the coronary anatomy is known, and many units adopt the policy of early (within a week) angiography of infarct patients without contraindications to revascularisation. 6 Non-ST elevation acute coronary syndromes (p. 156). 7 Acute myocardial infarction in a unit where primary angioplasty can be performed
How sleeping less than 6 hours affects your health After being awake for almost 14-16 hours, our body demands sleep. Minimum sleeping time required for a healthy mind and body is 7-8 hours. Although, this duration varies according to age. Because generally speaking, where a child can sleep for 12-14 hours, grownups can sleep for not more than 9 hours. Sound sleep is very essential otherwise, it can be harmful for our health. Let’s see how sleeping for less than 6 hours affects our health. Headache, weight gain and poor vision: When you sleep for less than 6 hours a day, it can not only give you headache all the time but can lead to a poor vision also. And if continued for a long time, may hamper your eyesight. The lesser you sleep the more weight you gain. And after-effects of gaining weight could be even more hazardous. Memory loss, heart disease, infection: Sleeplessness can have an adverse effect on one’s memory too. A person may find it difficult to remember even simple things. Also, infections can take a longer time to heal because sleep is something that stabilises and balances everything that goes wrong while we are awake. If we don’t get proper sleep, the process of healing takes longer. Lack of sleep can also elevate blood pressure which ultimately affects the heart. Urine overproduction, stammering and accident: Sleeping slows down urinating process but when you are awake for longer hours, you might have to urinate more than usual. Lack of sleep can also make you stammer while speaking. If lack of sleep continues, you may not be able to communicate properly. When you do not have sound sleep, your mental condition would not be stable because of declining concentration. You can be accident prone if you drive in such a condition. These are just a few of the ill effects. Sleeping for less than 5 hours is far more dangerous than you can even think. From behavioural to mental to physical effects, it can harm you in many more ways, So, have a sound sleep to avoid complications in life.
This ordinarily consists of monitoring of  is suspected. heart rate and rhythm,  repeated measurement of systemic arterial pressure by cuff,  obtaining chest radiographs to detect heart failure,  repeated auscultation of the lung fields for pulmonary congestion,  measurement of urine flow,  examination of the skin and mucous membranes for evidence of the adequacy of perfusion, and
THE HYPERDYNAMIC STATE. MI with hyperdynamic state—that is, elevation of sinus rate, arterial pressure, and cardiac index, occurring singly or together in the presence of a normal or low left ventricular filling pressure—and if other causes of tachycardia such as fever, infection, and pericarditis can be excluded, treatment with beta blockers is indicated. Presumably, the increased heart rate and blood pressure are the result of inappropriate activation of the sympathetic nervous system, possibly secondary to augmented release of catecholamines, pain and anxiety, or some combination of these.
