Hypertensive emergency is having severely elevated blood pressure (>180-220 mmHg/120-130 mmHg) that is complicated by progressive target end-organ damage of the central nervous system, heart, kidneys, or the gravid uterus.
There is no definite blood pressure threshold for the diagnosis of hypertensive emergency.
Most target end-organ damage happen with diastolic blood pressure of ≥130 mmHg.
Hypertensive urgency refers to patients with severely elevated blood pressure (>180/110-120 mmHg) but with little or no evidence of acute end-organ damage.
The clinical differentiation between hypertensive emergencies and urgencies is dependent on the presence of target end-organ damage rather than the level of blood pressure.
Not only does taking antihypertensive drug at bedtime lead to better control of blood pressure (BP), it nearly halves the risk of cardiovascular events compared with dosing upon waking, according to the Hygia Chronotherapy Trial — thus debunking the long-held belief that antihypertensives should be taken in the morning.
The lower threshold for hypertension diagnosis in the 2017 ACC/AHA hypertension guidelines does not necessarily entail more pharmacological treatment, says a leading expert in cardiology during a presentation at AFCC 2018, who highlights that the first key step for managing hypertension is lifestyle modification.
While intensive treatment of hypertension may benefit patients with a higher risk for cardiovascular disease (CVD), it may do more harm than good for those with a lower CVD risk, reveals a stratified analysis of the SPRINT* study.
Self-monitoring of blood pressure (BP), when used by general practitioners (GPs) to titrate antihypertensive therapy, led to significantly lower BP in people with poorly controlled BP than titration guided by clinic BP readings, the TASMINH4* study finds.
A polypill containing fixed low doses of three antihypertensive drugs led to better blood pressure (BP) control without increased adverse effects compared with usual care among people with persistent hypertension, according to the TRIUMPH* trial.
Blood pressure (BP) readings appeared to be similar regardless of whether BP measurements were attended or unattended by staff, nor were CV outcomes different between the two techniques, according to a post hoc survey on participants following the SPRINT* trial.
Noninvasive cuff-measured blood pressure (BP) is significantly different from invasive method of measuring intra-arterial BP, particularly for individuals with pre- or stage 1 hypertension in whom intra-arterial brachial systolic BP (SBP) is underestimated and diastolic BP (DBP) is overestimated by cuff measurement, reveal recent meta-analyses, suggesting a need for improved noninvasive methods of measuring BP.
Increasing the dose of loop diuretic at hospital discharge of patients with heart failure (HF) was not associated with a reduced risk of hospital readmission for HF or any cause contrary to previous reports suggesting that such a dosing strategy could reduce readmission, according to a study presented at the 21st Asian Pacific Society of Cardiology Congress (APSC 2017) in Singapore.
Lowering systolic blood pressure (SBP) to <120 mm Hg and diastolic blood pressure (DBP) to <70 mm Hg during treatment in high-risk patients was associated with an increased risk of cardiovascular (CV) events, except for stroke, according to pooled results from the ONTARGET* and TRANSCEND** trials.

Several high-density lipoprotein (HDL) functionality parameters, which are linked to HDL roles on cholesterol metabolism, endothelial protection and antioxidant/anti-inflammatory defence, contribute to an increased risk of incident acute coronary syndromes and its manifestations in individuals at high risk of cardiovascular disease, a study reports.
A wearable arrhythmia detection device, the AliveCor KardiaBand (KB), demonstrates moderate accuracy for diagnosing atrial fibrillation (AF) in comparison with a 12-lead electrocardiogram (ECG), as shown in a recent study. However, combining the automated device diagnosis with the electrophysiologists (EP) interpretation of unclassified readings improves overall accuracy.
