#1
REVIEW
Richard Body, Edward Carlton
Cardiac troponin (cTn) is a highly specific biomarker of myocardial injury and is central to the diagnosis of acute myocardial infarction (AMI). By itself, however, cTn cannot identify the cause of myocardial injury. 'Troponinitis' is the condition that leads clinicians to falsely assign a diagnosis of AMI based only on the fact that a patient has an elevated cTn concentration. There are many causes of myocardial injury other than AMI. Clinicians are required to differentiate myocardial injury caused by AMI from other causes...

REVIEW
Jagdeep S S Singh, Louise M Burrell, Myriam Cherif, Iain B Squire, Andrew L Clark, Chim C Lang
Natriuretic peptides, especially B-type natriuretic peptide (BNP), have primarily been regarded as biomarkers in heart failure (HF). However, they are also possible therapeutic agents due to their potentially beneficial physiological effects. The angiotensin receptor-neprilysin inhibitor, sacubitril/valsartan, simultaneously augments the natriuretic peptide system (NPS) by inhibiting the enzyme neprilysin (NEP) and inhibits the renin-angiotensin-aldosterone system (RAAS) by blocking the angiotensin II receptor...

REVIEW
Semhar Z Tewelde, Amal Mattu, William J Brady
Less than half of patients with a chest pain history indicative of acute coronary syndrome have a diagnostic electrocardiogram (ECG) on initial presentation to the emergency department. The physician must dissect the ECG for elusive, but perilous, characteristics that are often missed by machine analysis. ST depression is interpreted and often suggestive of ischemia; however, when exclusive to leads V1-V3 with concomitant tall R waves and upright T waves, a posterior infarction should first and foremost be suspected...

A 52-year-old man who had a history of 34 pack-years of smoking presented to our primary care clinic with a 1-month history of episodic chest pain. The episodes occurred once every night while the patient was at rest, lasted for 15 minutes, and resolved without intervention. Sublingual..

#11
REVIEW
Francesco Pelliccia, Juan Carlos Kaski, Filippo Crea, Paolo G Camici
Originally described by Japanese authors in the 1990s, Takotsubo syndrome (TTS) generally presents as an acute myocardial infarction characterized by severe left ventricular dysfunction. TTS, however, differs from an acute coronary syndrome because patients have generally a normal coronary angiogram and left ventricular dysfunction, which extends beyond the territory subtended by a single coronary artery and recovers within days or weeks. The prognosis was initially thought to be benign, but subsequent studies have demonstrated that both short-term mortality and long-term mortality are higher than previously recognized...

REVIEW
Wilbert S Aronow
Factors predisposing the older person with acute myocardial infarction (MI) to develop heart failure (HF) include an increased prevalence of MI, multivessel coronary artery disease, decreased left ventricular (LV) contractile reserve, impairment of LV diastolic relaxation, increased hypertension, LV hypertrophy, diabetes mellitus, valvular heart disease, and renal insufficiency. HF associated with acute MI should be treated with a loop diuretic. The use of nitrates, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, aldosterone antagonists, beta-blockers, digoxin, and positive inotropic drugs; treatment of arrhythmias and mechanical complications; and indications for use of implantable cardioverter-defibrillators and cardiac resynchronization is discussed...

REVIEW
Jun Yang, Jimmy Shen, Peter J Fuller
Hypertension is a leading cardiovascular risk factor that remains difficult to manage in a large segment of the population. Secondary causes of hypertension, which are amenable to targeted treatment or even cure, may contribute to poor blood pressure control. The most common endocrine cause, primary aldosteronism, requires biochemical screening as there are often no symptoms or signs other than hypertension. Screening tests should be done after adequate preparation to optimise the results and minimise the confounding effects of diet and medications...

MULTICENTER STUDY

BACKGROUND: For acute myocardial infarction (AMI) without heart failure (HF), it is unclear if β-blockers are associated with reduced mortality. OBJECTIVES: The goal of this study was to determine the association between β-blocker use and mortality in patients with AMI without HF or left ventricular systolic dysfunction (LVSD). METHODS: This cohort study used national English and Welsh registry data from the Myocardial Ischaemia National Audit Project...

BACKGROUND: Validated diagnostic algorithms in patients with suspected pulmonary embolism are often not used correctly or only benefit subgroups of patients, leading to overuse of computed tomography pulmonary angiography (CTPA). The YEARS clinical decision rule that incorporates differential D-dimer cutoff values at presentation, has been developed to be fast, to be compatible with clinical practice, and to reduce the number of CTPA investigations in all age groups. We aimed to prospectively evaluate this novel and simplified diagnostic algorithm for suspected acute pulmonary embolism...

#16
Olfa Hamzaoui, Thomas W L Scheeren, Jean-Louis Teboul
PURPOSE OF REVIEW: Norepinephrine is the first-line agent recommended during resuscitation of septic shock to correct hypotension due to depressed vascular tone. Important clinical issues are the best timing to start norepinephrine, the optimal blood pressure target, and the best therapeutic options to face refractory hypotension when high doses of norepinephrine are required to reach the target. RECENT FINDINGS: Recent literature has reported benefits of early administration of norepinephrine because of the following reasons: profound and durable hypotension is an independent factor of increased mortality, early administration of norepinephrine increases cardiac output, improves microcirculation and avoids fluid overload...

REVIEW
Pasquale Santangeli, J Eduardo Rame, Edo Y Birati, Francis E Marchlinski
Advanced heart failure (A-HF) is characterized by progressive symptoms of heart failure despite optimal therapy. In patients with A-HF, ventricular arrhythmias (VAs) are common. Clinical studies evaluating different therapies to prevent VAs had very limited representation of patients with A-HF. Among antiarrhythmic drugs, only amiodarone reduces VAs, although its use may be associated with increased mortality. Catheter ablation with substrate modification is effective to achieve VA suppression in patients with A-HF, including those with left ventricular assist devices...
