Background: Hypertensive heart failure (HHF) is the commonest form of heart failure in Nigeria. There is paucity of data in Nigeria on 24-hour Holter electrocardiography (24-HHECG) and important predictors of arrhythmias among HHF patients.
Objectives: To determine the 24-HHECG characteristics among HHF patients. To determine the clinical and echocardiographic predictors of arrhythmias detected using 24-HHECG among HHF patients.
Methods: A total of 100 HHF patients as well as 50 age-matched and sex-matched apparently healthy controls were prospectively recruited over a period of 1 year. They all had baseline laboratory tests, echocardiography, and 24-HHECG.
Results: Hypertensive heart failure patients had significantly higher counts of premature ventricular contractions (PVCs) than the controls ( ≤ .001). Ventricular tachycardia (VT) was recorded in 29% of HHF patients as compared with controls who had no VT on 24-HHECG. The standard deviation of all normal to normal sinus RR intervals over 24 hours (SDNN) was abnormally reduced among HHF patients when compared with controls ( = .046). There was positive correlation between atrial fibrillation (AF) and the following parameters: PVCs ( = .229, = .015), New York Heart Association (NYHA) ( = .196, = .033), and VT ( = .223, = .018). Following multiple linear regression, left ventricular ejection fraction (LVEF) ( ≤ .001) and serum urea ( = .037) were predictors of PVCs among HHF patients. Serum creatinine ( ≤ .001), elevated systolic blood pressure (SBP) ( = .005), and PVCs ( ≤ .001) were important predictors of VT among HHF patients.
Conclusions: Renal dysfunction and reduced LVEF were important predictors of ventricular arrhythmias. High counts of PVCs and elevated SBP were predictive of the occurrence of VT among HHF patients. The NYHA class and ventricular arrhythmias have a significant positive correlation with AF. The SDNN is reduced in HHF patients.

Inpatient versus outpatient diagnosis of heart failure across the spectrum of ejection fraction: a population cohort study.

Background: Early heart failure (HF) diagnosis is crucial to ensure that optimal guideline-directed medical therapy (GDMT) is administered to reduce morbidity and mortality. Limited access to echocardiography could lead to a later diagnosis for patients, for example, during an HF hospitalisation (hHF). This study aimed to compare the incidence and outcomes of inpatient versus outpatient diagnosis of HF.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer with residual invasive disease after neoadjuvant systemic therapy have a high risk of recurrence and death. The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with trastuzumab alone.
Methods: We randomly assigned patients with HER2-positive early breast cancer with residual invasive disease in the breast or axilla after neoadjuvant systemic treatment with taxane-based chemotherapy and trastuzumab to receive T-DM1 or trastuzumab for 14 cycles.
