Comparison of different frailty instruments for prediction of functional decline in older hypertensive outpatients (HYPER-FRAIL pilot study 2).

BACKGROUND AND AIMS: Few studies have evaluated frailty in older hypertensive individuals and the most appropriate tools to identify frailty in this population have yet to be identified. This study compared the performance of six frailty instruments in the prediction of 1-year functional decline in older hypertensive outpatients. METHODS: The HYPERtension and FRAILty in Older Adults (HYPER-FRAIL) longitudinal pilot study involved hypertensive participants ≥75 years from two geriatric outpatient clinics at Careggi Hospital, Florence, Italy, undergoing identification of frailty with four frailty scales (Fried Frailty Phenotype, Frailty Index [FI], Clinical Frailty Scale [CFS], Frailty Postal Score) and two physical performance tests (Short Physical Performance Battery [SPPB] and gait speed). Prediction of 1-year functional decline (i.e. a ≥ 10-point Barthel Index decrease between baseline and follow-up) was examined based on ROC curve analysis and multivariable logistic regression. RESULTS: Among 116 participants, 24 % reported functional decline. In the ROC curve analyses, FI (AUC=0.76), CFS (AUC=0.77), gait speed (AUC=0.73) and the SPPB (AUC=0.77) achieved the best predictive performance, with FI ≥0.21 and CFS ≥4 showing the highest sensitivity (82 %) and negative predictive value (91 %). Frailty identified with FI, CFS or physical performance tests was associated with an increased risk of 1-year functional decline, independently of baseline functional status and comorbidity burden. CONCLUSIONS: FI, CFS and physical performance tests showed similar predictive ability for functional decline in hypertensive outpatients. The CFS and gait speed might be more suitable for clinical use and may be useful to identify non-frail individuals at lower risk of functional decline.

Tolerability of Antihypertensive Medications: The Influence of Age.

INTRODUCTION: Despite high prevalence of hypertension, few studies have analysed the adverse effects (AEs) of antihypertensive medications, especially in older patients. AIM: To investigate the prevalence and associated factors of antihypertensive-related AEs, focusing on the influence of age on treatment tolerability. METHODS: We retrospectively investigated antihypertensive-related AEs in patients evaluated at the Hypertension Clinic of Careggi Hospital, Florence, Italy, between January 2017 and July 2020. Multivariable regression models were generated to analyse variables associated with AEs in the overall sample and in participants ≥75 years. RESULTS: Among 622 subjects (mean age 64.8 years, 51.4% female), the most frequently reported AEs were calcium-channel blockers (CCB)-related ankle swelling (26.8%) and ACEi-induced cough (15.1%). Ankle swelling was more common in older patients (35.7% vs 22.3%, p = 0.001; odds ratio [OR] 1.94, 95%CI 1.289-2.912) and was independently associated with Body Mass Index (BMI, adjOR 1.073) and angiotensin-receptor antagonists (adjOR 1.864). The association with BMI was confirmed in older patients (adjOR 1.134). ACEi-induced cough showed similar prevalence in younger and older patients (13.9% vs 15.6%, p = 0.634), being independently associated with female sex (adjOR 2.118), gastroesophageal reflux disease (GERD, adjOR 2.488) and SNRI therapy (adjOR 8.114). The association with GERD was confirmed in older patients (adjOR 3.238). CONCLUSIONS: CCB-related ankle swelling and ACEi-induced cough represent the most common antihypertensive-related AEs, also at old age. Older patients showed a two-fold increased risk of ankle swelling, that was also independently associated with BMI. ACEi-induced cough had similar prevalence at younger and old ages, being independently associated with GERD.

Prevalence and correlates of frailty in older hypertensive outpatients according to different tools: the HYPER-FRAIL pilot study.

OBJECTIVES: To date, few studies have investigated frailty in hypertensive individuals. This study aimed at identifying the prevalence of frailty in a sample of hypertensive older outpatients using six different identification tools. Clinical correlates of frailty and agreement between different frailty definitions were also investigated. METHODS: The HYPER-FRAIL pilot study recruited hypertensive patients aged at least 75 years from two geriatric outpatient clinics of Careggi Hospital, Florence, Italy. Four frailty scales [Fried Frailty Phenotype, Frailty Index, Clinical Frailty Scale (CFS), Frailty Postal Score] and two physical performance tests [Short Physical Performance Battery (SPPB) and usual gait speed] were applied. The Cohen's kappa coefficient was calculated to assess agreement between measures. Multiple logistic regression was used to identify clinical features independently associated with frailty. RESULTS: Among 121 participants (mean age 81, 60% women), frailty prevalence varied between 33 and 50% according to the tool used. Moderate agreement was observed between Fried Frailty Phenotype, Frailty Index and SPPB, and between Frailty Index and CFS. Agreement was minimal or weak between the remaining measures (K < 0.60). Use of walking aids and depressive symptoms were independently associated with frailty, regardless of the definition used. Frailty correlates also included dementia, disability and comorbidity burden, but not office and 24-h blood pressure values. CONCLUSION: Frailty is highly prevalent among older hypertensive outpatients, but agreement between different frailty tools was moderate-to-weak. Longitudinal studies are needed to assess the prognostic role of different frailty tools and their clinical utility in the choice of antihypertensive treatment.

Screening for cognitive impairment in older adults with hypertension: the HYPER-COG study.

Hypertension is a major risk factor for dementia. Yet, the most suitable cognitive screening test for hypertensive patients has yet to be identified. This study investigated cognitive impairment in hypertensive older adults and compared the discriminative ability of the most widely used cognitive screening tests. The study involved hypertensive patients aged 65+ without prior diagnosis of cognitive impairment, from the Hypertension Clinic of Careggi Hospital, Florence, Italy. Mini Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), MiniCog and Clock Drawing Test (CDT) were administered, using a comprehensive neuropsychological assessment as gold standard. The ROC curve analysis and the paired chi-square test were used to compare the discriminative ability, sensitivity and specificity for cognitive impairment of the different screening instruments. Cognitive impairment was diagnosed in 37% of 94 participants (mean age 76, 55% female), mainly involving attention and executive functions. The MoCA (AUC = 0.746), the MMSE (AUC = 0.689) and the MiniCog (AUC = 0.684) showed similar ability in detecting cognitive impairment, while the CDT had a poorer discriminative capacity (AUC = 0.535). The sensitivity of MoCA (80%) and of MMSE/MiniCog combination (74%) was higher in comparison with MiniCog alone (49%, p = 0.007 and 0.004, respectively), while MiniCog achieved the highest specificity (88%, p < 0.001 vs all). Cognitive impairment was detected in more than one-third of hypertensive older adults without prior diagnosis of dementia. MoCA, MMSE and MiniCog showed similar discriminative ability for cognitive impairment, with MoCa and MMSE showing greater sensitivity and MiniCog the highest specificity.

Hypertension management in frail older adults: a gap in evidence.

Hypertension management is challenging in frail older adults. The balance between treatment risks and benefits may be difficult to achieve due to an increased vulnerability to treatment-related adverse events, and limited evidence is available to support clinical decisions. The effects of frailty on blood pressure are unclear, as well as its impact on antihypertensive treatment benefits. Appropriate blood pressure targets in frail patients are debated and the frailty measure which best inform clinical decisions in hypertensive patients has yet to be identified. Therefore, hypertension management in frail older adults still represents a 'gap in evidence'. Knowledge of currently available literature is a fundamental prerequisite to develop future research and may help to implement frailty assessment and improve hypertension management in this vulnerable population. Given these premises, we present a narrative review illustrating the most relevant issues that are a matter of debate and that should be addressed in future studies.

Carotid Thrombosis in a Crack Cocaine Smoker Woman.

INTRODUCTION: We report a case of stroke in a crack smoker with occlusion of the middle cerebral artery and a large thrombus in the carotid artery. Case Presentation. A 34-year-old female presented with left upper arm weakness, associated with paresthesia with onset of symptoms more than 24 hours before. Angio-RM sequences showed an area of ischemia, with occlusion of the M2 segment of the middle cerebral artery. Carotid ultrasound showed a soft plaque with distal end floating. Anticoagulant treatment was started, and seriated ultrasound evaluations showed its gradual dissolution. CONCLUSIONS: In atherothromboembolic stroke from carotid thrombosis, repeated ultrasound studies may be useful for either diagnosis and monitoring the efficacy of anticoagulant therapy.

[Ictus dopo una seduta dal parrucchiere.] / Stroke after a visit to hairdresser.

Riassunto. Le dissecazioni delle arterie cervicali (DAC) sono una causa inusuale di ictus ma il loro tasso di prevalenza cresce fino al 20% nella fascia di età giovane-adulta. In molti casi le dissecazioni si associano a rare malattie connettivali come la sindrome di Ehlers-Danlos, di Marfan, la fibrodisplasia. I fattori di rischio esterni principali sono rappresentati da bruschi traumi cervicali come negli incidenti stradali o, meno frequentemente, da procedure meno cruente come la manipolazione e l'iperestensione prolungata del collo. Diversi casi di DAC sono presenti in letteratura dopo sedute chiropratiche, procedure odontoiatriche ed endoscopiche. Noi riportiamo un insolito caso di dissecazione della carotide interna di sinistra causata da iperestensione del collo occorsa dopo uno shampoo dal parrucchiere.

The CHA2DS2-VASc score and Geriatric Multidimensional Assessment tools in elderly patients with persistent atrial fibrillation undergoing electrical cardioversion. A link with arrhythmia relapse?

INTRODUCTION: The CHA2DS2-VASc score is widely used for stroke risk stratification in patients with atrial fibrillation (AF). Our endpoints were to evaluate in an old population undergoing electrical cardioversion (ECV) of persistent AF if the CHA2DS2-VASc was associated with some of the Geriatric Multidimensional Assessment tools and with the presence of sinus rhythm at the follow-up. METHODS: We enrolled all the consecutive patients admitted in a day-hospital setting aged ≥60 years. The Mini-Mental State Examination (MMSE; neurocognitive function), the 15-item Geriatric Depression Scale (GDS; depressive symptoms) and the Short Physical Performance Battery (SPPB; physical functioning) were administered before ECV. RESULTS: Between 2017 and 2019, 134 patients were enrolled (mean age: 77±9 years, range: 60-96; men: 63.4%; EF: 60±12%). Hypertension was the most frequent comorbid condition (82.1%). The CHA2DS2-VASc score was 3.8±1.6. Abnormal values of MMSE, GDS and SPPB were observed in 7.9, 19.8 and 22.3% of cases, respectively. There were significant correlations between the CHA2DS2-VASc score and the MMSE (p=0.008), the GDS (p<0.001) and the SPPB (p<0.001). Depressive symptoms increased CHA2DS2-VASc correlation with SPPB of about 20%. CHA2DS2-VASc score was higher in patients with arrhythmia relapse (p=0.048; mean length of follow-up: 195 days). This association persisted even after adjustment for amiodarone therapy. CONCLUSIONS: The CHA2DS2-VASc score significantly correlated with neuro-cognitive performance, depressive symptoms and physical functioning. It was also associated with AF relapse. Accordingly, in the elderly, the CHA2DS2-VASc could help quantify thrombo-embolic risk, give an indication of frailty status and help to choose between a rate- and a rhythm-control strategy.
