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 Aortic regurgitation The incompetent aortic valve allows regurgitation of blood from the aorta to the left ventricle during diastole for as long as the aortic diastolic pressure exceeds the left ventricular diastolic pressure. Symptoms: Occur in the late stages of disease and include exertional dyspnoea, fatigue, palpitations (hyperdynamic circulation) and exertional angina. General signs: Marfan’s syndrome may be obvious. The pulse and blood pressure: The pulse is characteristically collapsing; there may be a wide pulse pressure. The neck: Prominent carotid pulsations (Corrigan’s sign). Palpation: The apex beat is characteristically displaced and hyperkinetic. A diastolic thrill may be felt at the left sternal edge when the patient sits up and breathes out. Auscultation): A2 (the aortic component of the second heart sound) may be soft; a decrescendo high-pitched diastolic murmur beginning immediately after the second heart sound and extending for a variable time into diastole—it is loudest at the third and fourth left intercostal spaces; a systolic ejection murmur is usually present (due to associated aortic stenosis or to torrential flow across a normal diameter aortic valve). Signs indicating severe chronic aortic regurgitation: Collapsing pulse; wide pulse pressure; long decrescendo diastolic murmur; left ventricular S3 (third heart sound); soft A2; signs of left ventricular failure. Causes of chronic aortic regurgitation: (i) Rheumatic (rarely the only murmur in this case), congenital; (ii) aortic root dilatation—Marfan’s syndrome, dissecting aneurysm. 8• THE PATIENT WITH A MURMUR 305 a b Valve cusps often thickened and calcified Left ventricle may be hypertrophied Ascending aorta may be dilated Systole Diastole S1 A2 P2 S1 Ejection click (Suggests congenital AS) Normal Mild S1 S1 Moderate S1 P2 A2 S1 Severe Reversed S2 Single (S2)
SAMIKSHA HEART AND DIABETIC CARE IN YELAHANKA Echocardiographic findings in certain cardiac abnormalities It is important to be aware that modern colour flow mapping is so sensitive that small amounts of regurgitation are often detected from quite normal valves. Deciding whether these jets are significant can be difficult and requires experience. Mitral stenosis Thickening and doming of the mitral valve leaflets is visible on M mode and 2D scanning , It may be possible to measure the valve area by planimetry . Secondary changes such as left atrial size and the presence of rheumatic disease of other valves can be seen. Doppler interrogation of the jet of blood entering the left ventricle through the mitral valve will enable estimation of the valve area by a formula called the pressure half-time equation This will usually give accurate and consistent estimates of the valve area and is especially useful for serial measurements over months or years. It will also be possible to detect associated mitral regurgitation with Doppler. Mitral regurgitation and mitral valve prolapse Here the mitral valve may appear normal and abnormal co-aptation of the leaflets is not usually visible . The left atrium will appear enlarged if significant chronic MR is present, and if this is severe left ventricular dilatation will be present. If the MR is due to mitral valve
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
