Cardiac Troponins are specific to the cardiac myocyte and have central role in diagnosing ACS. They are found to be specific and sensitive, in addition they also provide prognostic information which adds to their utility in managing and diagnosing of CAD. Constant change in levels of Cardiac Troponins is required to define ACS. CKD patients with advanced disease have misfortune of having both a dramatically high rate of cardiac mortality paired with decreased ability to detect, it due to elevated Cardiac Troponin levels.[6]. mortality in dialysis patients from cardiovascular disease is substantially higher than the general population as depicted in Figure1.

Figure 1: Cardiovascular disease mortality by age, race, and gender in the general population and in dialysis patients. Cardiovascular mortality is defined as death due to arrhythmias, cardiomyopathy, cardiac arrest, myocardial infarction, atherosclerotic heart disease, and pulmonary oedema. Data from the general population are from the National Centre for Health Statistics multiple cause of mortality files 1993. Data from dialysis patients include haemodialysis and peritoneal dialysis combined from USRDS 1994-1996. Reprinted with permission from Am J Kidney Dis 32[Suppl 3]: S115, 1998.

Often, persistently elevated levels of troponins are found in patients having CKD, which reduces the specificity of the test considerably. Increasing levels
Troponin is present in heart muscle cells. If damage is done to these cells, it releases troponin into the bloodstream. The blood level of troponin, during a heart attack, increases within 3-12 hours from the onset of chest pain. It peaks between 24-48 hours and returns to a normal level over 5-14 days (Koutoukidis, Stainton & Hughson 2013, p. 506). The indicators include acute myocardial infarction, severe pulmonary embolism causing acute right heart overload, heart failure, and myocarditis. The normal value of Troponin I is <20
The results also showed that patients in the treatment group had a lower risk of hospitalization for heart failure, progression of albuminuria, and loss of kidney function

We used clinical and biochemical data derived from the DaVita database. The study population (N=420,255) included subjects undergoing hemodialysis in DaVita facilities across the US during the period of 2004 to 2011.
Recommended blood tests include CBC, creatinine, BUN, electrolytes (including Mg and Ca), glucose, albumin, and liver function tests. Thyroid function tests are recommended for patients with atrial fibrillation and for selected, especially elderly, patients. Blood test, serum NP/BNP levels are high in HF; this finding may help when clinical findings are unclear or other diagnoses (eg, COPD) need to be excluded.
The leading cause of death among all dialysis patients is cardiac disease which all too often results in sudden cardiac arrest or sudden cardiac death. Sudden cardiac arrest or death is the consequence of fatal arrhythmias that result in the loss of cardiac function. According to the Cleveland Clinic, the most common life threatening arrhythmia is ventricular fibrillation. With these fatal
Heart failure diagnoses are carried out by a specialized medical practitioner. It comprises of holistic patient health review such as patient medical history, patients symptoms, lungs con-gestion assessment, carrying out physical activity under observation, assessing for fluid re-tention (edema) and also assessing risk factors such as Coronary artery diseases, high blood pressure, Diabetes. According to tansy (2010 1399), heart failure can be diagnosed using different test methods such as Blood tests. This helps to check for any possible diseases in the thyroid, kidney or liver that can cause heart problems (NT-proBNP). N--terminal pro-B-type natriuretic peptide is a chemical checked in the blood. When the heart is under stress BNP is secreted
In the United States, over 5 million patients have heart failure (HF) and approximately 20 million patients have chronic kidney disease (CKD). Both conditions are linked by multiple risk factors including obesity, hypertension, diabetes mellitus, tobacco abuse, and increasing age. The presence of HF increases the risk of CKD and vice versa. Nearly one third of all patients with HF and 70% of Medicare patients with HF have Stage III CKD or greater and approximately 50% of dialysis dependent end stage renal disease (ESRD) patients will develop HF.
Type 1 cardiorenal syndrome is defined as “Acute worsening of heart function leading to kidney injury and/or dysfunction” (7). Examples include acute heart failure, acute coronary syndrome or cardiac surgery resulting in worsening of renal function, or contrast induced nephropathy after coronary angiogram (8). 27 to 40% of patients admitted to the hospital with acute decompensated heart failure (ADHF) appear to develop acute kidney injury and fall into this clinical entity (9, 10). These patients experience higher morbidity and mortality, and longer hospital stay (2).
Cardiovascular diseases has affected large number of population worldwide and in developed countries it is responsible for half of all deaths, coronary artery disease (CAD) alone is responsible for 1 of every 4.7 deaths in the United States (Eichner et al., 2002).
Left ventricular dysfunction that leads to reduced ejection fraction (< 2.8 ng/mL that was associated with NSM. In contrast, a couple of recent large studies suggested that the peak serum troponin I > 0.1 ng/mL within 72 hours of patients with SAH were associated with NSM (Kilbourn et al. 2015; Malik et al. 2015). A high-sensitive troponin T may assist for early detection of cardiac leakage. This is due to that cardiac enzymes might be released early after SAH, and thus have key values for early identification for developing NSM (Oras et al. 2015). Although, creatine kinase –MB level cannot distinguish the NSM and acute myocardial infarction
“Every twelve minutes another name is added to the national organ transplant waiting list” (Donate life America, 2009) (para. 1&2). The National Center for Health Statistics (2008) website states “652,051 people die every year of heart disease, 75,119 die of diabetes, 43,901 die of nephritis, nephritic syndrome, and nephrosis [kidney disease].”
Blood tests will be done to assess troponin I, troponin T, creatine kinase (CK) and myoglobin which are classified as cardiac serum markers (Cardiac Emergencies, n.d.).
causes it is associated with increased mortality. It is estimated that 4,270 patients die from kidney
As the population ages heart failure is expected to increase exceptionally. About twenty-two percent of men and forty-four percent of women will develop heart failure within six years of having a heart attack. “Thirty years ago patients would have died from their heart attacks!” (Couzens)
